@basedbagel - I've heard a tentative theory that makes sense about a decade ago...
The gist is, that male gayness is a byproduct of a gene that is beneficial in females. Supposedly it contributes to a personality type that is happier, and generally more pleasant to be around. It's along the same lines as the sickle-cell anemia gene. It can cause problems for some individuals, but overall, is more of a help than a hindrance.
And gay dudes are generally much more pleasant company than dykes.
