it can be, same as femininity though

Reine Maskulinität nicht, nein.

No. I don't think behaving toxic is a characteristic of masculinity, but a sign that someone's an asshole.

Not when I do it.

Nö, man kann sich durchaus "männlich" verhalten, ohne die Verhaltensweisen, die toxic masculinity ausmachen, zu verkörpern. Der Begriff wird nur gerne von einigen Leuten so ausgelegt, dass alles Männliche toxisch sei.

Not in and of itself. However anything can easily become "toxic" if left unchecked

*hyper*masculinity is toxic. Masculinity itself, probably not - it's natural, maybe even fundamental as one side of a metaphysical polarity.

I can't seem to find the LD50 on that, sorry.

Nah.
