@Tattie what upsets me about this as a person who's both autistic and testosterone dominant, is that no ones considering how kids smashing things up is likely a self regulatory behavior. No one is asking this child what's so overwhelming that they need to break something about it, no one is redirecting that behavior into something safer and no one is teaching that child how to communicate or set boundaries. These children will be perpetually punished for doing the things that get them into a more stable mindset then be taught no alternative. Im sure as one develops, it is then easier to internalize the message that their biology is bad, they were born bad and are now entitled to being bad. Anyone with any alternative in how they communicate or regulate become something to resist, bolstering their entitlement. And this is how you get incels and misogynists and transphobes etc.

(Side note: respectfully, as if your brother is mansplaining to you how hormones work, as if you havent undergone an entire hormonal transition. Miss me with that.)
