Does this photo mean my crush is gay?

[Jo]

I got on Facebook to check out this guy I'm interested in, and one profile picture was with these crazy anti-gay demonstrators with these goofy posters. From the context I think he was just pointing out how funny they were; he's not joining in the gay bashing. He looked really hot in the picture, too . Anyway, my point is would a straight guy find that funny enough to post, or does mean he's gay? I'm female so of course I don't want that to be the case.
