It's like the day after the election, half the population started engaging in WW2 cosplay.
There are more Rastafarians in America then there are actual Nazis, and I'd wager very few people in this rally even know the definition of a Nazi, let alone are one.
You know what I think? I think you don't actually care about free speech. A Nazi (a real, card-carrying Nazi) drove a car through a group of leftist protestors and killed an innocent young woman. He took away, by force, her right to freedom of expression.
But I notice you haven't voiced any concern about that - you only care about freedom of speech to the extent that it's used to protect Nazis (and those who associate with them). But when it comes to protecting the free speech of protestors who disagree? All of a sudden, your deep concern is nowhere to be found. Give me a break.
What you are talking about is completely orthogonal to the first amendment. Everyone has a right to speech and everyone is protected from vehicular assault & murder by law. I hope that everyone on Hacker News condemns that act of violence.
Could you please point to the source of your claim that he was a "card-carrying Nazi"?
