There's 100% nothing wrong with being a man, and there's nothing wrong in taking pride in it. There is, however, a ton of societal pressure to do dangerous, harmful things to ourselves to "prove" our manliness/masculinity. Ignoring pain and sickness because fear of being weak, taking a lesser role in the development of our children because it's seen as girly, harassing women because it's "what guys do", doing dangerous stunts to impress the guys; these are all harmful behaviors that are all rooted in a need to appear masculine.

This is toxic, and we need to recognize that without getting defensive over it just because it's what we know. We can do better for eachother and ourselves and recognition of this fact is a necessary first step.
