Sorry, hate to break it to you, but these illiberal forces are a clear and present danger to this comfortable society you call home.
No, it's the last gasps of a dying breed of racists, empowered by the Internet and that look a lot more popular than they are due to media focus. Nazis are lame, but you leave them alone and there's nothing to fuel the fire. You send out counterprotesters, get in fights with them, act like these people are on the verge of starting a civil war and in their minds you've proved them right (delusional though they may be), and they get energized and then you have a real problem.
Kicking nazis off the Internet is one thing, but yours (and the grandparent) is the language that causes the slippery slope arguments. That people can't even discuss the issue of free speech without being assumed to be nazi sympathizers or "cryptofascists" or whatever we want to label people we don't agree with isn't ok.
Someone having a debate about the right of nazis to use modern services is not by extension a nazi.
