"There are reasons why this is so"
And I want to know what they are. I've not heard anything convincing yet. Noone has offered an explanation of its wrongness here. The most that's been offered is a claim that we're disposed against it. But that's a bare fact of biology, not a moral claim; it won't tell us anything about how we should think about someone who doesn't share the aversion that most putatively have, or whether that's a moral problem or simply an interesting personality quirk.

See my reply to Roota below about the parent thing.
