You must have in mind,that we(the community)can't be serious all the time.
Try to differ a joke from a serious comment,everyone call other people fags,gays,idiots,etc.Check some signatures and usertitles,it is a very common thing.
EDIT : Sometimes it is a way to approach new people,make friends.Strange way to do it,but it happens,just be ready for it.

Troll him,or ignore.
Such thing isn't relevant when playing games,chatting,etc.
