I do understand "Toxic Masculinity". It's right in the word and is much like how conservatives would blame " black culture" for the societal ills of African Americans.
You simply denying that that's not what it is doesn't debunk anything.
And we have a term for societal expectations already and it's called gender roles. Which isn't a loaded admonishment like toxic masculinity.
All of feminism revolves around the critique of men which is an inalienable trait.
