I don't go to women's marches, I don't go to many marches at all actually. I'm skeptical of that mode of protest.
Men and women both have problems in society, and for those interested you might learn how a lot of these problems intersect with class, race, health, et cetera. Speaking of "men" for example is problematic, as not all men experience the world the same way. What does the sentence "it's harder being a man" even mean? On this forum it often means that being a beautiful woman is easier than being an ugly man -- I agree.
The other issue pointed out is that average women have an easier time than average men getting first dates without regard to quality. That's completely true. In that aspect of life, women have it substantially easier.
There are plenty of issues with being a woman in the USA. For example the maternity leave policies and day care costs are among the worst in the developed world. That will be abstract to 22 year-old posters but it will not be so in ten years when you're 32. That's not an issue for rich women though.
