What we're seeing is likely an attempt to suppress the more toxic and dangerous traits associated with masculinity. Yes, it causes some kids some suffering, but if the alternative is that they grow up to fight or rape or hurt their peers and colleagues, is there a chance that it's worth it?
I say this, by the way, as someone who has been in a suicide watch room in jail once as a young adult because I refused to answer questions. It was terrible, but after 24 hours I feel it had a lasting positive effect on me. I've been much less rebellious since then. I'm also thankful it happened before my tendency to act out ended up hurting other people.
