"What of those do you consider toxic?"

None of these traits are toxic in general, but due to group dynamics they often lead to toxic behavior. When guys want to show how masculine they are (and I think most are not conscious of this), they start doing stupid things. Bullying and disrespectful behavior, dangerous driving, not letting others contribute, not admitting errors, etc. That's why a culture that rewards "masculine" behavior is bad for collaboration.
