I'm sorry if I'm intruding. I've had experiences of my own of being treated badly because of being male that might answer your question:
as a kid I was the prime target of bullying at my school. Whenever a boy would hit me, we would both get punished. When a girl hit me, I would get punished. Teachers openly said "you only hit women with flowers" to justify this. Teachers would also routinely say out loud boys were lazy, not as smart as girls.
I ended up spending two years in therapy because I said I wanted to be a girl. I'm not transgender, I just wanted to be treated fairly and my child mind had identified that with being a girl.
I've only recently come to accept that being a man is not a bad thing. I used to not have male friends and be afraid of them. I used to believe women are better (they're not, but the shitty ones are better at concealing it).
The social narrative about boys and men is truly damaging, especially to boys who don't naturally tend towards the typically masculine traits and will be tempted to just dismiss their own gender as less than.
Boys should be encouraged to become men, not stigmatised for it.
When my husband and I tried to have kids we were told many many times that adoption was not for single men or male couples by adoption agencies. When we trie surrogacy instead, the psychiatrist that was to assess us told us that as men the process would be longer and more harduous. We ended up spending two years being judged by her. Most of that time we had to talk about incest.
Of course when the kid came we had no right to parental leave or other benefits, because we were not women. The world of parenthood is dominated by women, and jealously guarded at that. Becoming fathers was a long string of humiliation (thankfully our kid is wonderful and it all was well worth it).
I work close to upper management in a large NGO. We have an unwritten but strictly applied policy that top management needs to be 50/50 in terms of gender. Most applicants for upper management jobs are men. This means often candidates are rejected because of their male gender (even thoughvit's technically illegal). Middle management is mostly women and nobody cares. Somehow I don't believe we wouldn't care either if it was mostly men.
Sometimes it feels like equality is not for men. It makes me feel like a second class citizen.
It used to be that gay men's tendency to have many short-time sex partners was seen as perverted and wrong. Then as a society we mostly moved past that and accepted consenting adults do whatever they want.
We did the same thing with female promiscuity, from demonization to celebration, especially in mass media. Sex and the City was over 25 years ago and it was not a trailblazer.
Somehow this understanding hasn't been extended to heterosexual males. We still present womaniers as people who "use" women as if women were unable to make choices of their own and having sex with a man was taking something away from them.
