I do not have the relevant study comparing hetero married couples with adoptive lesbian/gay couples on hand, the numbers seemed pretty bad BUT compared to the abuse in institutions ->
-> it was comparatively not bad, and the takeaway was that abuse of children not with their biological parents is very high and that while there may be some difference between ->
-> on average hetero/lesbian/homosexual parents, the numbers are pretty high across the board and preferable compared to having the children in institutions instead of adoptive partent
So it is not a lesbian/homosexual/Hetero thing, it is more "Not your biological children" thing. Marriage with biological children best case scenario on average statistically.
