We may get more data on what happens to kids raised by gay adoptive parents, once there are more gay adoptions. (Or we may not, if the study results prove too controversial).
This is why homosexuals need legalized marriage. The second they acquire gay marriage, they will demand preference in adoption. And every one of those adopted children can be brainwashed to embrace the homosexual lifestyle.
That is the plan. The plan is to turn adopted children into fags and dykes, and they can’t demand adoption preference until they conquer legalized marriage. Then they will scream they were being discriminated against any time they are turned down for adoption, and the adoption agency will fold and give in.
This is the plan.
