@Thomas,
That's fine. That's a reading of what he actually said, though, which was "anyone who defends 'homosexuality' as 'genetic' is
homophobic."
Emphasis mine.
I've managed to make some real inroads with people using that argument, pointing to the science that supports it, etc.
You're right that "....and anyway it shouldn't matter" is compatible with the argument, but that particular argument is useful.
And I don't think implementing that argument makes me homophobic.
