I don’t think the discourse of rights is at all appropriate for framing adult fertility issues at all.
I tend to agree - and for anyone, straight or gay, male or female.
But it's nuance, isn't it? Because such a view could be seen as leading to the idea that lesbians or gay men shouldn't be allowed to be parents. Many of us can still remember when lesbians, who'd been in straight marriages, were denied care or custody of their children in divorce because they were lesbians. And so on.
A dear friend of mine is a father to 2 DC with two lesbian friends. It's a very seriously thought through family arrangement, and he loves being an active father. But when I expressed my strongly held view that surrogacy was beyond the ethical pale and should be illegal in any circumstance, he was equally convinced of the way this excluded many gay men from having their "own" DC. He saw it as a matter of rights as well.
And I can see his point of view. Except his point of view requires either being sure a man can find a 'charitable' surrogate, or overlooking the humanity of a woman who acts as a commercial surrogate. Or regarding the willingness of a woman 'renting' her body as a purely economic transaction.
Which it isn't. None of this is instrumentalist or economic. We are human beings, social beings with emotions and bodily integrity.
