Wrong way around. Using yr key, GG is gay.

And as others have mentioned, yr bee analogy is wrong, since you neglect the extreme consanguinity of those near-clones. But in general I agree with yr argument, although the burden is on you (or yr case) to show that inclusive fitness is better maximised in this way than by total obsession with making babies.

(I also think bisexuality doesn't really need an explanation, since rubbing rude bits together is obviously fun and social and good for power trips, etc, unless you've been socialised out of it [as I was and I gather you weren't]. It's *dedicated* gayness that's the puzzle.)
