Yes, this is a common thing gay parents do. (you're retarded)
As the son of lesbian mothers, I can vouch for this. I was raised as a girl solely because "meh, why not?" I still remember that awkard conversation with my mothers: "Mommy, why does my vagina go all hard and pointy when I see the other girls in the showers?" Thankfully they stopped addressing me as Shirley as soon as I started growing facial hair... at age 25.
As far as using specious anecdotal evidence to support a completely ridiculous premise, Hitler, Stalin, Hussein, Mussolini, Castro, Pol Pot, and hundreds of other dictators and despots throughout history were born to heterosexual parents. What does that tell you? If you answered "absolutely fucking nothing," congratulations on not being an imbecile.
