I think the West, at least, has a pretty grim culture that requires men to be manly where that is a penalty, and to conform entirely to a modern way of acting (passive and nonaggressive) where that is a penalty. As such, a man who complains or fights is less manly or a shitlord, respectively. We are vilified in every aspect, and it is (and the stats back me up here) ending in suicide. Women can shout and scream and attack, but a man who wants to retain his standing and his freedom has no recourse, and it's making us more bitter, bottled and lonely.
When I see this kind of complaint I think "what the hell West are you living in then?"
Now I'll grant you that I'm not the most social person, but I do interact with people voluntarily now and again, here in the deep red district I live in, and I have never felt like any of that was true. The West is not just one culture.
It's what happens when you have incumbent "Testosterone man" (eg, "strong-man", or "manly-man") culture (old world conservative views on being an adult male) not letting go, along with a strong and rising tide of "House husband" culture.
The two are mutually exclusive, but the proponents of both cultures don't care. If you are one of those, you get vilified by the other.
The issue, is that many millennials are actual more "otaku" culture than anything else. Having grown up under conditions where parents would rather that they by "safe" than socialized, most millennial boys/young men use digital communication as the first line of communication, rarely go out to do things (and so have difficulty scheduling a group outdoor activity, and if they do so, often have difficulty finding fun things to do with their time while out with friends), they tend to "do their own thing." rather than conform to either of the prior stereotypes being promulgated as the ideal.
Couple that with the inherent isolation of otaku culture, and you have people who get stuck in feedback loops about ridicule, and end up with bad self-image, and bad opinions of other people in meat-space, which reinforces the digital-only communication bottleneck that contributes to the isolation problem.
They tend to be a bit of both stereotypes-- (they can be gender-stereotype chauvinists, and they can also be very "genderfluid" as well. It's a mixed bag.) as such, the vocal groups in the "testosterone man" and "house husband" camps each see them as "THEM!", and there is no middle for them to feel accepted socially.
I would chalk this up to another casualty of the west's recent decent into outright "US/THEM!" thinking on every god damned thing, and the abandonment of reason for emotional decision making en-mass. Our media plays a significant role in this development, as the MSM has an invested interest in producing and sustaining controversy whenever and wherever possible. This includes culture shift issues.
If you note, the MSM has a difficult time understanding the millennial generation as anything other than "Those aberrant, lazy kids!"
