Are you objecting to women talking about men as a class by using your own sweeping stereotypes about sex.
I think gender is unimportant. It's as ridiculous as "whites" talking about "blacks" or "jews" talking about "christians", "gays" talking about "straights", "country people" talking about "gypsys" or any other arbitrary label you happen to want to apply.
There are good men, bad men, good women, bad women.
Try and complete the sentence:
All men and only men -
All women and only women -
I can't think of a single thing that goes into either one of those sentences. "Has the potential to give birth" doesn't even fit because transition male to female & female to male change that.
So why should gender effect anything? Even in what you might consider "clear cut" as men being physically stronger is incorrect. There are some women that are physically stronger than men and vice versa. As soon as you start talking about a "label" you are, by definition, make sweeping generalisations and imho unhelpfully so.
Sexism is something we've invented and need to uninvent to liberate society. So it goes back to my original point: I don't understand why a gender, so damaged by sexism, is so keen to actively promote it.
