Hate to be picky here, but last I checked there’s no cervix or uterus attached to a man’s colon. As such, how do you consumate a same sex marriage?
Not everybody that gets married has kids. This world is over populated anyways. We should not be looking to compete with China in this department.
Like most normal people, I don't want to think about it. It's the kind of thing that creeps out normal people, especially children who are naturally - - instinctively - - creeped out by homosexuality, despite all the best efforts of the liberal Democrat government schools to change human nature.
You'll have to ask a homo.
