I'm also chuckling to myself the apparent incongruity between the "trolling is a threat to democracy" line and the doctrinaire view of freedom of speech expressed in your sig. But then again, in your view, I'm probably an irrational threat to democracy because I enjoy trolling Nazis and white supremacists.
There's no incongruity there because I never said you shouldn't be allowed to troll Nazis, just that I find trolling for the sake of trolling to be unhealthy behavior. Remember, one of the key tenets of the concept of free speech is that I may not like the things you say, but I won't try to stop you from saying it.
