I'm beginning to really dislike the term hatred. It seems to be the default term thrown out by those who can't justify their ideology. I equally grow increasingly weary of the use of phobias to belittle those who oppose the agendas of one side or the other. This is a great example of intolerance, sense it is used against the person and not the issue. To me it is a sign of weakness. It merely tries to shove other peoples arguements under the rug, instead of dealing with them. The "Your views are invade because you're a hater" stance is an ad hominem attack and pretty much a waste of everyone's time.
You're right.
I think it is intellectual laziness (or ignorance) and ultimately comes down to dehumanizing someone who disagrees to the point of being a caricature, as I noted above. I find that people who do this tend to have limited exposure to diverse range of viewpoints. They surround themselves with people, media, and the like that put forth a viewpoint they already agree with. Insulating oneself is easier than thinking.
