I'm of the opinion that gay couples should be able to create their own families, and they should also have a right for a biological family. So yeah, while we should regulate this business to make sure there's no exploitation, we need to help gay couples if they want to establishb a family. Right now, it's a privilege for rich couples.
Rich couples, gay or straight, should not be allowed to buy children out of some unfortunate woman's womb either. You cannot regulate that which is inherently exploitive into not being so.
This is the first time that I've ever heard someone claim a "right to a biological family." The idea perplexes me.
What's with this idea that women could never be okay with having a baby for others who can't have one themselves?
