if you want to pull THAT card, Scotch-Irish, Nordics and Germans are more prone to become Alcholics.
Norse and German culture embraces gay ideas. (no pun intended, ew)
Russians in the western areas have the same thing. and Native Americans are living on patches of dirt given to them as repayment, of course they're going to look at the bottom of a glass, they were screwed.
You forgot that practicing homosexuals men are also far more likely to have been raped/molested when they were a child by an adult homosexual man. I doubt that all Russians and Native Americans were more likely than other nationalities or races to have been raped/molested as a child by an adult homosexual man....
