Gay adoption is problematic period... Recent study from the netherlands basically proved this one, confirmed what all thinking and honest people know.
In the netherlands there is no social stigma to being homosexual, or to children raised by them, yet children raised by such couples were found to be at much higher risk for all sorts of problems.
Even if they could (they can't) but even if they could prove a 100% genetic link to homosexuality, homosexual adoption is dangerous and hazardous to children.
Thank you, but I don't engage in arguments involving a false premise.
If X (where X is true), then Y. Such a thing can be debated.
