Well yeah, but like I said earlier, that'd only happen if the other side allowed it to happen. I can see it going in that direction if Annoying Orange hadn't won the election and started the pendulum swing, you know? As it stands, at worst we have people like Richard Spencer, who no one outside of a very small demographic takes seriously, because at least in America, we don't have much to afraid of in terms of people coming in and wrecking our stuff. In placed like Germany and Britain and France, where terror attacks seem to occur on a monthly basis, I could see how a national socialistesque party could come into power, because they have legitimate fuel for fear to use, and instead of acknowledging these fears as understandable and well conceived, the other side is trying to shout people down with claims of racism and Islamophobia, which is only making people genuinely start to hate middle eastern(er?)s and Muslims. It'd be like if the anti-muslim sentiment that was widespread after 9/11 didn't quiet down because the government told everyone to shut up about Islam instead of dealing with the issue. Eventually a party would come around that would promise to take care of the issue, and the people would be extremely accepting of it given the circumstances.
Any national socialists gaining power should be a clear sign to the opposition to get their stuff together.
