IT'S LONG BEEN a liberal assertion (and battle cry for gay marriage) that children of stable homosexual families fare as well as children of stable heterosexual families. That assertion may now be in doubt. I don't believe the research is dispositive, since (a) gay families don't beget children, they adopt (artifical insemination is a form of adoption to my mind); and (b) there is not yet a large enough research population to make any truly confident statement.

For those interested, there is more here and here.
