they will win those adoption cases. that will effectively be the "affirmative action" program for them - leveling the playing field for gays, since their marriages cannot directly produce children. the current judiciary will hand that to them also. it will take time, but they are patient.
Again, they are already there. Only Florida does not allow adoption by gays, and two states (oddly enough, Utah is one) that allows adoption by single people who are homosexual.
I guess it was all those gay couples who decided to adopt HIV positive babies back in the '80s and '90s that turned the tide on that issue.
