I'm actually impressed that you have found a good example of an animal that has gay tendencies. Props for that.

Now, based on this study it implies that there may be a hormonal imbalance between hetero and homo brains. Which to be honest, would definetly sometimes explain why there's such a predominant opposite sex tendencies, ala flamer or butch.

I think we're getting off the subject though. We're starting to get into some technical stuff about homo and hetero instead of focusing on the marriage aspect.
