My preference is to have both straight friends and gay friends. I don't like EITHER-OR questions. They almost always force you into a position you don't really want. Once you've chosen sides, other people feel forced to pick a side also. If asked an EITHER-OR question, I will always ask, "Can't I have both?"
I say, wherever you can find joy or enlightenment without significant side effects, go for it! I do know that both gay and straight people have been important role models for me. I think I've needed both!
