Even I’m worried about this and I couldn’t be more pro trans rights. But I think this isn’t a trans issue, it’s a surrogacy issue.
I’m not generally opposed to surrogacy, but I think it’s only acceptable when women who act as surrogates have absolute autonomy over their bodies and the babies they have. If they decide at any point up to the moment of formal adoption that they no longer want to give up the baby, they should be able to do so without facing any kind of penalty. There also needs to be a significant cooling off period so that the adoption process can’t be commenced right away (not sure if that is currently the law).
I also think we need to tighten up the law so that surrogates aren’t paid more than compensation for their actual costs / expenses. I think we have to be very careful not to create a situation where poor women feel economic pressure to be surrogates.
