People who try to get rid of toxic masculinity are not against masculinity.
Masculinity is not toxic by default.
"Toxic" masculinity is that false macho behavior that is actually harmful to others and the person exhibiting it. It's malice hiding behind the cover of being a "male" trait or "boys will be boys".
Examples would be being overly aggressive (to the point of happily inflicting harm or cruelty), overly competitive (to the point of obsession), overly confident (to the point of narcissism/arrogance), or overly sexual (to the point of being lewd or creepy).
I am a masculine man, and I reject toxic masculinity. Neither the woman in the OP nor others in this thread understand what "toxic masculinity" actually is and why it's bad.
