Well, at least the way I hear it used on the news, American conservatives are very different from Chinese and Russian conservatives.
Perhaps then, you should stop accepting what you hear on the news without critical analysis. It is invariably biased in some fashion, usually by lies of omission -- the most common of which, is that Group A is somehow so different from Group B as to be worthy of differential treatment. It does not make good news to say "We are 99.5% like these other people, but because of this singular thing in which we differ slightly in opinion on, we must dislike them." No, good news is "They are evil bastards with no redeeming qualities and we must punish them for this!" It feels better, more righteous. It satisfies our need for order in the world, this idea that the good are rewarded and the bad punished... and curiously, the good are always defined as "us" and the bad defined as "them."
Alas, American conservatives are not so different from conservatives anywhere else. Perhaps superficially. Perhaps in a great many ways that really don't matter... no different from driving on the left versus the right side of the road, or in how we dress or the slang we banter about. But it doesn't feel as emotionally satisfying. We want to be part of the superior group... therefore, some other group must be inferior, even if the inferiority is entirely socially constructed. And because we want this, we are eager to overlook similarity. Some people are eager to the point of violent opposition, like you are.
Twenty thousand years of human evolution says we are very, very much alike... and I assure you, every news channel, in every country, everywhere, says the same thing: "We're not like them!" Even if, on the whole, we very much are.
