I think if you make (negative) comments on religion, sexuality and race, you are bound to offend some people. Maybe it's a matter of opinion. But if he made an unsightly comment to the gay community at the gay parade, he will probably be deemed offensive too.
Huh. What do you think would be the gay parade equivalent of the pork-eating image?
Maybe a picture of a naked woman with the caption "I'm a heterosexual male, pussy is great, sucks to be you."
Mildly offensive, I guess, if you're extremely sensitive about your sexuality. Do you think someone should go to jail for displaying such an image during a gay parade?
Offensive enough to be sent to jail with murderers, thieves and rapists? You'd either have to be a ridiculously apologistic liberal or put the mental in fundamentalist to go that far.
Apologistic liberal? I know that term has different interpretations, but I've never seen it being associated with inhibiting free speech in order to not cause offense. It would be pretty silly if "liberal" ended up meaning "without liberty".
