> Is there a gay crime wave? I haven't noticed one.

I can think of two possible, orthogonal answers why that (sort of) fit the hypothesis:

- the key is not 'stable relationships with women' but 'stable sexual relationships';

- many gay men do have stable relationships with women, in the form of strong, non-sexual friendships.

[Edit: I neither support nor reject the hypothesis; I just don't think gay men are necessarily a good control group for it.]
