“Men will be men” just excuses the behaviour and ostracizes men who don’t do these things. It has less to do with their sex and more to do with how we raise men.
Toxic masculinity as a defence mechanism of patriarchal society is the main problem and “feminine”, “emotional” or “weak” men, or those not subscribing to heteronormative sexuality are targeted by the same types to uphold their status.
How does something like this not show up in tests?
