Remember, when you allow gay parents to have children, the children are completely under their care. I do not feel comfortable with gay men "spanking" and punishing children. Do you?
Even if most gay parents did not abuse their children, 47% of molestation cases come from within the family: fathers, stepfathers, and uncles. Allowing gay marriage endangers many more children.
Good grief! Your logic implies that the optimal conditions for raising a child is with two lesbian partners because men are more likely to molest a child. It is curious with your logic that you have a problem with Cheney's daughter.
"Aren't most gays raised by straight parents?"
How do you define straight. Here are some actual case histories.
1) Mother and father have several children. Fathers plays around with other women. Mother sexually abuses fathers favorite son. Son grows up gay. Dies of AIDS.
2) Mother dies when son is 13. Father uses his son like a woman. Son lives a gay life now.
3) Son around the age of 8 expresses positive appreciation of women in Sears catalog in scanty dress. Straight parents ridicule his interest. He is now a gay adult who wishes he could be attracted to women.
4) Straight couple has several sons, some currently straight, some gay. Father is a piggish skirt chaser. Two sons turned gay, one died of AIDS, but like(d) women as friends. Straight sons date women but don't particularly like them. A psychologist said the mother was the most malignant mother he had ever met. I surmise she is "killing" her husband by ensuring her sons will never reproduce.
As for not feeling comfortable with gay men "spanking" their children, I don't feel comfortable with straight men spanking their children. Spanking is seldom necessary in child discipline. Just check out that nanny program to see how discipline can be achieved without physical punishment.
