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.
I was going by my own experiences. At county fairs in upstate NY and Northern PA, the political parties, candidates and interest groups all set up informational booths alongisde vendors, travel agents, equipment dealers, etc in the exhibit halls. No, no one has a "right" to be there- but if the fair board bans one political group, it better ban 'em all, or there will be hell to pay (and rightly so.)
