Here's a gem that Statists propose from time to time: Seattle officials call for ban on 'potentially offensive' language
I've made this point before, but it bears refreshing from time to time. Polite speech needs no defense. The things that challenge us, that force us to grow and think, are often offensive because they break us out of our usual mental paradigms.
People get to be racist. They get to be sexist. They get to say stupid things. That doesn't make them right, but in protecting even that garbage, we open the door for when someone comes up with a a great idea that we should take seriously but we find challenging. In time, good ideas work, bad ideas don't and we discard the bad (which is why racism and sexism are waning, though they still do exist).
This is why the 1st amendment exists. There is no freedom from offense or hurt feelings. There is only freedom of thought and expression.
Eliminate that, and you eliminate real political debate, which I believe is the real goal. Statists, Leftists, Progressives, 20th Century Progressives or whatever you'd like to call them like Woodrow Wilson are simply fascists (don't believe it? Check out the Sedition Act of 1918).
Stifling free speech is a form of Statist control. Communists do it. Fascists do it. Leftist/Progressives do it. We shouldn't tolerate it.
