There's a counter-point to this that is likely to be unpopular, but it's deeply rooted in human biology and isn't going to go away any time soon. Attractive young women may have difficulty getting people to take them seriously, and have to deal with things like frequent unwanted sexual advances, but they have no trouble getting laid. Attractive young women have easy, practically unlimited access to sex (if they so desire). Unsurprisingly, this comes at a cost.

Meanwhile, while it's easier for men to be taken seriously, and they much less often have to deal with sexual harassment, they often have trouble getting laid—especially with the aforementioned attractive young women. It may be true that "the vast majority of guys...are simply not aware that women...go through this stuff all the time". But it's also true that the vast majority of women are simply not aware of how hard it is for young men, especially nerdy young men, to get appealing women to have sex with them. They would be utterly flabbergasted if they learned just how many computer geeks, science grad students, etc., have never even kissed a girl, much less had sex with one.

We see that there are plusses and minuses to each respective situation, but arguably men have it worse off, because women can complain freely of the terrible things they have to put up with, and they're generally met with sympathy by the mainstream (and backed by the full force of Federal law). Meanwhile, men who complain that attractive young women won't sleep with them are shamed and belittled, and told that no one owes them sex. Which is true—but is hardly helpful to the proverbial 40-year-old virgin.
