NOT easy to tell - and i am not 100% sure - but i'll say it is a dude. or at least he is legally considered a dude. this guy (if it is one) should NOT be holding up signs calling anyone "gay" for my guess is this guy makes Richard Simmons seem like Tommy Lee and he won't ever have to worry about some kid walking up to him and calling him "Daddy"! if it is a female - still - she should not be holding up a sign for the only guy she will ever get is "BOB" (as in: Battery Operated Boyfriend)
now - the babe to the right of this person (our right - his/her left) - SHE IS HOT! SHE can hold up whatever sign she wants - preferably one with her telephone number on it!
I went from guy to girl to guy to girl, then thought well his/her friend is hot, so it's the ugly friend syndrome. Either way, I agree there should be no gay bashing from this person.
