State agencies should review the specific living situation and review impartially on behalf of each child who needs a home. There should be no discrimination, period.
For the record, I am from Southampton County, Virginia. In my own, personal experience: every pedophile I've ever encountered was hetersexual; every gay person I know had straight parents; the gay parents I know are amazing, devoted, and the kind of parents I wish every kid had the chance to have.
You just can't judge ANYone by stereotypes.
