I see that literally every single person on the negative side of this argument (as in, not in support of this thread's proposed idea) continues to dwell in the realm of personal insult, hypocrisy, constant reference to strawmen and "concern trolling" (never heard that one before) and an unwavering refusal to ever directly address a question.
Even if you believed the question to be disingenuous or a strawman, you could... with very little effort, still address it legitimately. That's what you would do, if you had a legitimate answer. If not for the benefit of the person asking, for others reading the exchange.
Only legitimate questions deserve legitimate response. "You realize that what you said means X" is not a legitimate statement when it never meant X at all, and is clearly so. There's nothing to address, other than the use of such dishonest techniques.
I'm forced to conclude by the endless slippery bullshit and dodging of questions, coupled with the personal insults and blatant sexist double standards re: responsibility, that those posters are entirely dishonest, and fully aware of being so.
There's no slippery slope, other than in the deliberate obfuscations of Nehalem & Cybr.
Pregnancy & childbearing are exclusively in the realm of women. Men simply cannot experience them, so no "equality" is possible in that. In our society, and the rest of the developed world, a woman's sovereignty over her body is absolute. Therefore, men have no say about it, other than deciding to support a woman's choices or not. They're her choices, rightfully so, because she'll bear the consequences of them in ways that no man possibly can. That difference, that dichotomy, is part of the human condition, a function of gender & the extended childhood of our evolutionary heritage. Human childhood lasts a very long time in comparison to other creatures.
There is, however, usually equality in the creation of a fetus. In the most desirable situations for progeny, should progeny occur, equal responsibility exists in the need to support & nurture that child. It has always been so.
