If I am called a “racist,” I will consider that a fighting word, and probably get into a fight, even though I don’t like to fight.
I was called a “honky” once by a guy of the Mexican persuasion, and I asked him, nicely, not ever call me a “honky” again.
He, of course, did, and I told him that if he ever called me a “honky” again, I was going to knock him on his ass.
A few weeks later, he did, and I did.
He never called me a “honky” again!
I guess that what I am saying is that there are “fighting words.” People HAVE to understand that the “FReedom of speech” clause of the US Constitution DOES NOT give a person the right to mouth off and not have to suffer the consequences of said mouthing off!
So I guess “cracker” is out of the question.
Lesson learned
