It's not sexist to point out that men historically have held disproportionate cultural, social, economic, and political power and continue to do so to this day.
And historically men have fought wars, guarded borders, done very dangerous jobs, and so on.
Most men have not held power. A top 1% of men held power, and 99% of men did dirty and dangerous jobs at the bottom of the hierarchy, and worked worse than animals to try to provide for and protect their families.
Men give up seats on lifeboats for women, yada yada yada. Trying to frame this whole thing as "men vs women" is ridiculous, because men are so incredibly in favor of sacrificing themselves for women. Clearly other issues are involved than some "pure evil sexism".
