MizPiz said:Spitting wouldn't be my personal choice (a bit of an overreaction, I'd probably just continue to kiss, maybe be a bit more passionate about it), but yeah, your friend should have just ignored it.
I'd go with that too. To be honest, I've never seen someone else tell a couple to not kiss in the cinema ever, and given you did say that you are both disgusted by the act of two men kissing... I think your mate was possibly being led by his dislike of men kissing than the actual act of kissing.
EDIT: Yep, just saw the post where it was said he wouldn't have asked that if it were a heterosexual couple. In this case then, he was discriminating against them just because they were gay, and for that reason only he probably deserved to be spat in the face of, because people who discriminate for any reason are, in my opinion, scum.
