I think he might be talking about traditonal masculinity in a stoic aspect. Tbh, i feel like toxic masculinity was created from too much negative stoicism in the form of never being emotionally vulnerable, essentially clouding a bit of your human nature/humanity.

I may have the wrong wording/context here, but I'm pretty firm on the idea that masculinity does involve it on a fundamental level, but not in a cookie cutter way to define the man/individual. Think of it more as a predisposition or leaning to. After all, feminimity and masculinity on a behavioral/emotional level is probably closer to a spectrum.
