There is quite a big difference between parenthood + possible life threatening situation + all the "normal" changes that are part of pregnancy; and parenthood.
If it would be purely about parenthood, you would have a point but it is not. And maybe a conversation about the ability to opt-out of parenthood should be had but the conversation about abortion rights is not about parenthood.
I strongly encourage you to inform yourself about the consequence of the recent changes of abortion rights in America. It is not about parenthood, but health care.
