In reply to Mike Schinkel.

I have been reading all of these posts with interest, taking in the different sides of the debate...and then I read this:

"WordCamps could set a policy that you can wear whatever you want, but if another attendee finds it offensive you will be asked to remove it or change into something else, or to leave. No ifs, ands or buts."

OH HELL NO. In that scenario, we have the masses policing each other, everyone will expect to get their way, and no one wins. Can you seriously imagine being told to REMOVE YOUR CLOTHING because it offends someone? Please think about that. I would far rather say "don't wear any slogans or images on your clothing" than let attendees police each other.
