The thing is, being gay is probably a random distribution or even a gradient with no clear border, just like being "black" (a brazilian, a jamaican, a nigerian and a french blacks are all black but all very different, both in color gradient of their skin color and cultural meaning of it - it s almost meaningless), so it's probably as wrong to say "gay men are earning degrees faster than before" as to say "blue eyed tall people are earning degrees faster than before".

Or, in other simpler words, there are no gay men, just complex multi faceted individuals whose sexuality trends towards same sex mates amongs a myriad of other things happening in their lives.

I think your first sentence sort of debunks your point. If gayness is randomly distributed then we might expect there would be a similar ratio of educated to uneducated gays to that of society at large. The fact that the ratio is instead biased towards more educated overachievers in the gay community indicates that gayness confers some sort of statistical benefit in regards to achievement/education.

It plausible, but I think sexuality, emotional intimacy .. are key factors in ones life. I personally had other troubles regarding those and the day they went away I realized how my life would have been different if I could have just played the games my buddy played as teens while I was head stuck in the sand obsessing about some intellectual stuff.
