As always when people make these claims, you have a lot of far-from-proven assumption embedded in here, so the claim that society is "anti-male" rather than "less aggressively pro-male than it used to be" is unsupported.
A more subtle point would be that, to a marginal young male, it may be hard to tell the difference. Resentment is likely to be high to start with in someone struggling but consistently failing. This I find much easier to believe, and less wildly in contradiction to the evidence of my (male) eyes and the experience of people who grew up around me. But it's a hugely significant difference in what it implies about who should do what.
That's without getting into proving a correlation, let alone causation. The timelines don't seem to line up for your claim, IMO.
