To the poster claiming that surrogacy is the same as organ donation, there is one major difference there....
The surrogate is alive, the baby is also alive and growing inside of her, and that baby will then be removed from its mother at birth in order to be sold to the couple who wants it, and yes it is selling babies even if you’re only doing it for [hm] expenses.
Organ donors are, as a rule, dead. They don’t go through anything in order to donate their organs,even though they choose to do so in life, when it comes to the point where their organs can be donated, they’re dead and no longer in a position to be affected by it.
FWIW I don’t like the idea that some relatives are pressured into donating kidneys or a part of a liver either, but selling of organs is illegal, just as selling babies should be.
As for the OP needing to be tactful, why? The DH asked the question. If he didn’t want the answer he shouldn’t have asked. It really is that simple.
And for people stating that “unless you’ve been in a position to not be able to have children you can’t possibly understand,” quite apart from the fact that this line is trotted out in order to make people feel guilty, let’s look at it from another angle. Unless you have actually had children, carried them and given birth to them, you can have absolutely no idea what it’s like to carry a baby and then give it away, even without any complications. It goes both ways you see.
Infertility is sad, but unfortunately sometimes it is life. And just because something can be done, doesn’t mean that it should. Not being able to have children doesn’t entitle anyone to do whatever it takes to have one...
