I don't think it's about stupidity; it's about young men trying to fit into the world, to impress their peers. It's depressing to see from the article that there are women who buy into this too - presumably basically for the same reasons.
If kids aren't brought up with better values, with more self-awareness, greater self-esteem and more respect for other people then they become vulnerable, as they look for a way to be successful, to being influenced by arses like Andrew Tate, or religions (Christianity, Islam and Judaism are all historically misogynistic)
