This seems more of a clarification than an anything that will actualy change the practical situation. It may well be the case that being raised by a hetrosexual married couple is the ideal situation for every child (although it's by no means an absolute), but that is not an option available. Seems to me that being raised in by two people in a stable homosexual relationship is a better option than being raised in a childrens home.
Please read the links in comment 10 above, and then see if you hold the same opinion.
Those who study the subject without pro-homosexual bias come to the opposite conclusion.
