I thought I hammered the entire racist right pretty hard in my post. My point is, if we allow any one group (be it a political party, a religious organization or whatever) to be deprived of their rights, it's the proverbial camel's nose in the tent. Next thing you know, we have only one legal political party, one one approved religon- "Ein reich, ein volk." (Tr. = "One nation, one people.")
Someone put it very well sixty years ago. Forgive me if I misquote this a bit due to faulty memory:
"They came for the Jews, and I did not speak out, because I was not a Jew. Then they came for the Catholics, and still I did not speak, because I was not a Catholic. Then they came for the communists, the intellectuals, the freethinkers, the libertarians, and still I did not speak, because I was none of these things.
Then they came for me. And there was no one left to speak for me." - Anti-Nazi German citizen, quoted on his release from Hitler's death camps
But I'm still a bit mystified about what "right" you might think this bunch has to set up a booth at the state fair. If they want to set up a booth on a public street, in the park, or even hire a private hall and spew their "message", yeah fine, let 'em. But I'm perfectly willing for the organizers of the fair to make their own decisions about who gets a forum and who doesn't in this case. Its about agriculture, not political polemic.
"Free speech" doesn't mean that you always get to pick and choose the venue, place, and time. If I were to get up on a soapbox during the opening prayer in the Legislature in Mississippi and start spouting crackpot theories at the top of my voice, I'd be dragged off and probably be put in a rubber room, and rightly so. Time and place matter.
