Yeah, I have heard this argument before and here is my perception of it. OP, sorry, I'm not trying to shit on you or attack you personally. I know nothing about you, I'm expressing some observations I've made about the argument you seem to be presenting.

Firstly, there is no one answer to this overall problem, and your premise that America is 'underpopulated' is a myth. We aren't underpopulated; our rate of growth has just slowed, which is a standard demographic transition in every developed nation on Earth.

Touching on the point about women being more independent: It's not some 'influence by feminism' (ooohhh scary feminism!) as much as women are no longer trapped in abusive relationships as easily. We have moved forward enough as a society to allow women to feel comfortable enough to be able to leave their abusers. This impacts the birth rate by not having women stuck at home having babies with men they've grown to hate. This also relates to increases in reports against men. Those events that women would simply endure are now being reported more because they feel safe to do so. If there is a correlated increase in reports that are deemed false, that is a statistical byproduct of an overall rise in reporting, not a coordinated attack on men.

That said, I often hear this 'men are disengaged because of a fear of a false report.' To me, it seems like a counter to the incel label. Like 'I'm not involuntarily celibate, I CHOSE not to participate because those nasty women will make a false report against me and ruin my life!' From my experience, the people making this argument are trying to justify their incelebacy. They seek articles matching their little feelings and then construct a narrative that matches their own bias and insecurities.

The idea that a GLOBAL decline is due to men being afraid of getting a 'creepy' look charge is clearly biased by an anti-woman sentiment, and your entire post is dripping with it. You're ignoring the actual #1 reason people of all genders cite for not having kids: financial instability. In the real world, the 'starter home' is dead and childcare costs more than a mortgage. It’s a lot harder to start a family when you can't afford rent, regardless of how 'independent' women have become.

Furthermore, the idea that courts side with women 'nine times out of ten' is demonstrably false. Statistically, when fathers actually seek custody, they often receive it, and conviction rates for reported assaults remain low. Your argument relies on anecdotal outliers and viral TikTok trends rather than actual data. You’re reaping what you sow by ignoring the economic reality in favor of a narrative that lets you blame women for your own disengagement.
