Random thought of the day...

As I sit here watching the news talk about the ongoing hatred towards gays, especially of those who want to adopt or already have, I am struck with a thought; why is it "ok" (or becoming more increasingly ok) for some kids to have 2 moms(and/or dads)? Yet when it comes to a child who is adopted by a more "conventional" family(ie 1 mom & 1 dad) the mother,who's DNA that child carries, gets demoted to merely a "birthmother"? A child who is adopted isn't allowed to have 2 mothers. For the most part, there usually HAS to be a distinction of some sort. Anybody care to weigh in?
