No that's not how it works, and you are mixing things up here. Toxic behaviour does go deeper, but here it repurposes standard stereotypes as a way to regulate gender relations. It is not the act of being masculine in itself that is a problem.
But using gender in a way that ostracize and encourages violence absolutely exists and is definitely toxic. It just happens to target men more as it pushes them to gain back power and authority. Having an accurate and specific term for the problem makes sense.
But that’s the issue - ‘toxic masculinity’ isn’t accurate. It’s become a generalized term that presumes men all have the same nature. Sure, gender roles exist and it’s important to discuss how they impact our everyday lives. But once we get into violent extremes like rape, using broad cliches like toxic masculinity are useless.
Most hockey kids come from the same privileged background. They live in the same progressive and egalitarian society that teaches mutual respect, not to cheat, kill, hurt, rape, etc. Yet a few do it anyway. What triggers one kid to become a rapist when the other kids in the same situation don’t? The answer won’t be found by pawning off responsibility to society, by blaming men’s nature, or through superficial slogans. We're not in a sociology class, we're discussing a violent crime.
