I don't know
So not a speech issue.I'm not defending the right to assault someone. I'm simply suggesting that it's the ASSAULT that should be punished, not the fact that the assault was on some group that the person doesn't like. That's the equivelant of a parent punishing a child more harshly because he punched his sister, who he doesn't like rather than the brother that he does like. Are we punishing the assault or the fact that the assaulted one happens to be someone the assaulter doesn't like.
The issue with the sign would not be the speech, but the hiring practice. The sign would be evidence.Hiring is most definitely a speech issue. I can't hang a sign in my window that says "Irish need not apply". If that isn't speech, I'm not sure what is.
The term "political correctness" is usually used by right-leaning people against a left mainstream, but I think such false assumptions as well occur on the right side of the spectrum and are challenged by left-leaning people.
"Not learning from mistakes is worse than committing mistakes. When you don't allow yourself to make mistakes, it is hard to be tolerant of others and it does not allow even God to be merciful."
And I find it odd that you reject the legal systems of the US *and* every other other nation that has ever existed. It's an unusual position for someone who values order as much as you do.
