There isn't a "crisis in masculinity."
There are just guys who can't cope with there being any standards or expectations for their behavior at all after being told they could literally do whatever they wanted and treat people like property.
There's a reason every proposed "solution" is misogynist as hell and involves forcing women into a social position where their lives, bodies, and livelihoods are entirely controlled by men.
Because these men are pigs and want to live life on easy mode.
