The way I see it is that gays who want to adopt do it because they really want children. Therefore, they they most likely provide a very loving environment for that child. That in itself should make up for any shortcomings having two parents of the same sex would present.

Preventing gays from adopting has much more to do with the national homophobia than it does with protecting the interests of the children. Don't beleive me? Well, take a look at this list of potential parents

-White Supremecists
-Far out cult members.
-Crack addicts
-Convicted felons (murderers, bank robbers, etc)
-Sex offenders
-Welfare moms
-etc.

Nobody seems to have a problem with these people having kids, so why just gays? God forbid Steve and Larry want to adopt, but that creepy guy who hangs around the middle school with a camera can have kid (assuming he finds a woman to legally have sex with). There's a lot more to being good parents then just being Mommy and Daddy.
