A very clear difference between the Left and Conservatism is that the Left has shown itself to be very adept in the use of hatred as a political motivator. In polite conversation most Americans would happily acknowledge that racism, sexism, and all of the other -isms that are active components of discrimination and prejudice are very dark parts of humanity's collective gestalt, and would very much like for these aspects of human nature to cease to exist.
What won't be discussed in polite conversation, however, is the application of the emotional response to publicized hatred as a means of control of a political point of view. Take, for instance, the over the top coverage of the George Zimmerman murder trial. If an analyst were to take apart my words here today I'd be accused of being a racist because I didn't refer to the case as the "Trayvon Martin murder trial". Well, while that attitude wouldn't have a lot of merit even while the trial was still in progress, the audience receptive to that sort of dangerous rhetoric would be incited to call me down for my racism, and it is entirely possible I would be the target of some of the death threats Zimmerman faces even to this day.
The fact of the matter is Zimmerman is not a racist, as evidenced by the FBI's admission that they were not able to find any sort of racially charged motivations for his following Martin the night of the incident. That, however, isn't critical to the core of the message from the hate-baiters that Zimmerman is a racist, that hatred fueled his murder of Trayvon, regardless of the facts being found to prove no murder took place in a court of law, and that anyone who supports Zimmerman is a racist just as guilty of spreading hatred and danger to the communities of America as those very lynch mobs who murdered so many black Americans in decades passed.
The Left doesn't even try to square their use of hatred as a tool against the realities presented to the public they're trying to drive toward their goals. The general theory on the Left is that the public either isn't paying enough attention to reality, or that the public will listen to the Left's version of reality before thinking for themselves. Sadly, this directed use of hatred as a political motivator has shown itself to be extremely effective throughout humanity's history.
Conservatism doesn't allow for hate to be a component of our psyche because hate is damaging to the soul. Of course we all feel hate from time to time, and Conservatives engaged in politics often feel it most when battling Statists, or when confronting infringements on individual sovereignty by an ever strengthening government. We simply know how to shunt that emotion out and channel the adrenaline rush it gives us into a productive avenue. For a Conservative, to give into an emotional response generated by a stimulus and allow for that emotion to motivate our discourse is anathema to our moral core. There are those who allow emotion to control their actions, but one of the planks of Conservatism is to address negative stimulus with a rational, measured response.
The Left truly knows how to channel hate. They know how to enrage a populace to action using hate as the progenitor to violence, all while sitting back and allowing for the incited rage to be blamed on the people and not the politician or media figure. A mob is a very effective tool because it substitutes the will of the individual for the will of the mob, thereby eliminating rational thought about the motivations of the mob by any of the individuals that make up its numbers. Because mob mentality can be so very successful in accomplishing a goal, regardless of the moral efficacy of that goal, the Left has seen fit to use hatred as a driving force for much of their rhetoric. Think about the "war on women", the "war on poverty", the "war X"... The Left paints their opposition as waging wars against everything the Left is for because it galvanizes their constituencies into joining up against the oppressive opposition.
A prime example would be the "war on women" rhetoric during the Sandra Fluke fifteen minutes of fame. Conservatives do not want to prevent women from being able to obtain contraception. That has rarely been the case, and most certainly isn't the case in the modern era. The Left, however, neatly painted Sandra Fluke as being oppressed and that the Right was denying her access to free contraception because the argument at the time was that forcing religious organizations who provide private health coverage for their members and employees to fund the purchase of contraception violates the religious organizations freedom to practice their religion as they see fit, even if that practice denys insurance funding for contraception. This isn't a stance grounded in hate, as the Left would purport, but a stance grounded in faith and the religious interpretation of the Bible by Catholics and other organizations. This doesn't deny contraception; individuals are entirely capable of obtaining low cost contraception absent funding from their employer's health care coverage. The opposing view is that contraception is a civil right to women, and that the college Fluke was attending owed it to her to provide it free of charge based on this premise. The stance that free contraception is a civil right for women is an untenable stance to hold, as there is no language in the Constitution or the Civil Rights Act that protects a woman's right to free contraception. The Left's rhetoric, though, was very effective in making it seem like the Right hates women because of their defending of religious organization's First Amendment rights.
Of note, this issue has yet to be adequately resolved. Instead of addressing the issue head on, the Administration and Congress has deigned to delay the potential issues this creates until after the Affordable Care Act is actually stood up, since the potential of infringement of a protected right is not an actual infringement, and thus the religious organizations suing the Government to resolve this issue have been found to not have standing due to their rights not currently being infringed.
The Right doesn't see hate as an avenue to success because hate is dangerous. There is no way to prevent it from being felt by humanity, but there is a way to stymie the effects it has on rational thought. Conservatism's goal is to empower the individual. A single individual consumed by hate isn't dangerous to society as a whole. Plainly put, a group of individuals seeking a common goal will focus on the goal because the accomplishment of that goal is the motivator for the individuals making up the group, not the emotional response their hatred may have on their state of mind. Groups of individuals are also self policing. If the goal is shared by all in the group those who harbor hatred as a motivator within the group will be quelled or removed based on the damage their hatred causes to the goal's odds of accomplishment.
The Left, on the other hand, wants to focus hate because hate clouds the rational responses of human beings. Without rational responses to stimuli people tend to be very malleable when grouped together and focused, lending themselves to a mob mentality. The Left will do everything it can to subsume the individual in order to create a mob mentality that will be driven by hate toward a common goal, absent rational thought about that goal within the mob, and thus more likely to accomplish the intended goal without resistance to the methodology by which that goal is accomplished. This is especially true when that methodology is detestable, as most hate-baiting is seen to be when addressed in polite discussion.
This is one of the many diametrically opposing characteristics that separates Leftism, or Statism, from Conservatism.
