Okay let's just assume kids of gay parents are slightly more likely to be gay and or experiment with gay sex.
So what? Who cares! Homosexuality is not a disease, sheesh.
131,729 same-sex married households
514,735 unmarried same-sex households
Thirty-one percent of the married couples and almost 14 percent of the unmarried couples said they were raising children
Nearly 2 million children under age 18 were being raised by at least one gay or lesbian parent
Sample size is not an issue. There are more than enough gays to be able to get valid sized samples.
