Is it "Politically Correct"...

My understanding is that immediate incitement to violence - something like, "Hey, that guy there is a commie! Get him!" - can be made illegal and is in some places.General advocacy - like, "Commies should be lynched!" - is protected speech.Unless someone more lawyerly than me beats me to it, I might try to find some cites when I have time.

Well, I couldn't find any examples where organizations were punished for advocacy of illegal activities. Either such a thing just isn't done in this country (the US), or my Google skills are seriously awful.The closest I could find is the Communist Control Act of 1954. But it isn't clear to me whether it was passed to punish the Communist Party for advocating something or for actually doing things. Also, the intent of the law was really more to prove how patriotic the members of Congress were, so it was never enforced and so never tested in the courts.I am reminded of the defunding of ACORN and current efforts to defund Planned Parenthood, but those are for those organizations' activities or alleged activities, not for their advocacy.Finally, there's the famous (at least for First Amendment nuts like myself) case of Brandenburg v Ohio, which declared unconstitutional a Ohio law that made the mere advocacy of terrorism to accomplish political reform.That case involved an individual, not an organization, but the decision was pretty clear: unless the speech actually incites imminent lawless action, it is protected speech: I suspect that any attempt to punish an organization for advocacy of violence in a manner that was not seen to incite imminent lawless action would face the same fate. But then, you never know what will happen until an actual case comes before the nine people who are currently on the Supreme Court.

If you look at the history of the Jim Crow era South and the history of when and why those statues were originally erected, the you'll see that those chants pretty much are what those statues are about.
