You're on the attack over some commenters who affirm the reality of "female" vs "male".
Social constructs are abstractions, not necessarily based on reality. Feelings do not change facts; nor can facts be changed to fit one's sensibilities.
I didn't think I was "on the attack." Could you point out where you were reading an attack in my comments?
I asked why "pregnant person" was a confusing term and defended it on the basis of inclusivity. Social constructs are indeed not based on immutable truths, they reflect our beliefs and feelings. It seems reasonable to me to consider the beliefs and feelings of others when perpetuating social norms. Mother is an ambiguous term when we're talking about child bearers. Not everyone who bears a child is a mother and not every mother bears children.
