Responding to "Homosexuality is wrong, the same way incest is wrong"

Meandering:

Sure, Sam Harris says "let's agree morality is about maximising wellbeing". I am on board, that's what I think it should be about. And if someone thinks it's about something else, I'm going to try and explain why I think it's a bad idea.

However, from a philosophical point of view, all he's actually doing is excluding certain people from the discussion. I am fine with that, but I also like to keep in mind that if you ever want to bring other people round (those who don't agree about what morality should be about) you need to explain why your goals are better, not simply tell them they can't be part of the discussion.

Under Harris' definition, which most civilised people would agree with (after some make irrelevant extra points about god), homosexuality is in no way a danger to anyone's wellbeing and so is not a problem.
