You should reread what he said. You apparently understood it very poorly.
Either that or you're implying your gay friend is stupid... I doubt that was your intent though.
I missed the 'like' bit when I read the comment, my bad.
It's still a shitty comparison though.
EDIT: Shit, I should've gone with the "your implication about me being stupid made me sad because i take everything people say on the internet personally"-charade.
Too late now I guess.
