Well, since you are more interested in snide comments, there is probably no point.
You're (probably intentionally) missing the point. Sure, the two groups are different. The key point is that groups of people who espouse and enact ideologies that hurt large numbers of people can rightly be blamed for the consequences of those actions, even if some of their neighbors strongly disagree. People didn't condemn the Nazis because of their taste in clothes but because their ideology, which they put into horrible practice, hurt a lot of people because of their commitment to racist ideas. People condemn ISIS and Al Qaeda because the hurt innocent people because of their over weaning commitment to religious ideas. People condemn Mao and the Soviets for hurting innocent people out of a commitment to a political ideology. You understand this far, yes?
Furthermore, when the Nazis got attacked or ISIS gets bombed, few plead for sympathy for them or suggest we need to understand their positions with nuance
American conservatives similarly hurt a lot of innocent people, because of their overbearing commitment to economic and political ideologies. So, that can rightly be condemned. Furthermore, when the consequences of their actions actually backfire and hurt these same conservatives, are we suddenly supposed to have sympathy for them or look at their position with nuance? To contrive an example, it's a bit like suggesting we should have sympathy for the victims of an industrial accident when the accident is the release of a lot of poison gas killing a bunch of Nazis in the course of moving the gas to Auschwitz or something.
In other words, if people take actions that they know will hurt many many people, they're not in a position to beg sympathy when the consequences blow back onto them.
