It's all too predictable that your posts are being misinterpreted OP.
It's an interesting question. I personally think that those saying 'many men would not choose to carry the baby if it became feasible' are wrong. I think they are overlooking what we are already seeing.
We are already seeing TM elbowing their way into women's spaces, women's sport's, attempting to simulate periods, demanding gynaecological care, trying to induce breast milk, creating neo-vaginas (it's worth remembering that the latter often involves considerable expense and an ongoing physical burden, yet it doesn't deter them)
Do I think if science were to advance sufficiently to permit men to carry babies and it was to become an increasingly streamlined process, men wouldn't take it? I do think they would, in significant numbers, because many men already so inclined see the ability to gestate a baby as 'power'
Let's not overlook women either. They would likely become the biggest proponents of it! We've seen how many women endorse their children's desire to change sex, either in order to win 'best most caring mummy' status or straight munchausen's-by-proxy and some even start pushing it on their toddler children. Celebrities have been quick to embrace it. They'd be the first to jump on the bandwagon. As, they have been with surrogacy to have children close together or preserve the integrity of their vaginas. 'Oh look my husband is having our daughter, and I'm soooo proud of him, it just wooorrks for us, and leaves me free to never have to push something from my vagina'
It would affect the status of women massively. Many women take a derogatory view of SAHM, or women who have more than a couple children even now, men being able to have children would further devalue what women do hugely.
I do think it would free women up to secular working more hours, however. And attitudes would change. Just not in a good way.
