I know right? And I'm aware that not everyone who does EVERYTHING on that list is a Nazi, but for most of those items they're either a Nazi or a Nazi apologist, so...
The thing is, a lot of people won't say right out if they're a Neo-Nazi or subscribe to Nazi ideology, so I have to have some sort of criteria of rooting people out. Like one dude I ran into on tumblr had a swastika on his blog and followed and reblogged tons of Nazi bloggers and claimed he wasn't a Nazi. I used to often interact with him to tell him to leave a friend of mine alone, but it put me in danger because it exposed me to more hardcore, affirmed Nazis. So I don't take chances anymore.
