Grandparent was arguing that people can't handle free speech and that:
> Speech needs to be protected, but when it starts to encroach on my pursuit of happiness it's a problem. Facebook, Twitter, etc don't need to become chan sites.
I hear this a lot, particularly from the left (although the right does it too), on the grounds of protecting people from "harmful" speech. I disagree with that, which is why I responded, because I don't think enough people know about the modern interpretation of free speech and the long, storied history it has (not just in the US but everywhere). I certainly had no idea before I started reading.
> I'm also wondering why the great examples of free speech that people reach for are always racism.
It's not that they're examples, it's that the landmark Supreme Court cases that established our modern understanding of free speech typically involved the KKK and nazis (c.f. National Socialist Party of America v. Village of Skokie). In other words, people with horrible beliefs are the only reason why you can stand on a street corner and preach about socialism, communism, anarchy, etc (which might be "horrible beliefs" too, depending on the individual). 100 years ago, someone distributed a gentle poem by a socialist and was put in jail, and it was legal. Do you want to go back to that? Because it is absolutely possible.
