Yes, and 'being foolish' is legal. I don't have to like it in order to defend it.

I have a lot of experience being picked on and bullied in school for having unpopular opinions (I didn't like what the 'popular' kids liked - and early on, being crippled didn't help).

I believe the best defense against this sort of thing is publicity. Hold idiots up to the light and put their stupidity on display for all to see (and mock).
