Its an objective fact among every country that publishes crime statistics. These countries all vary widely in every other metric you can imagine (social, economic, political etcetera). But, crime being disproportionately commited by men is a universal constant. Nobody has an objectively correct answer to this question, it's just a prompt for discussion. Share your opinion, whatever it may be. However, please don't be a dick to other commenters. Disagreement, good faith, many view points and discussion is the goal here.
The way boys play can lead to acute ostracization if the rule is discriminatory towards you or even if you just happen to get unlucky where girls will often make exceptions to those rules to avoid a peer being ostracized
Growing up this was not my experience at all with girls. Maybe if you’re neurotypical and/or cis then girls are like that, but I got ostracized by most of my female peers from early elementary school (and the majority of my male peers wouldn’t give me the time of day to begin with because I was a ‘girl’). The ways girls can be cruel to each other for arbitrary reasons is really jaw dropping if you haven’t experienced it firsthand. Maybe it’s different now than it was ~30 years ago, but I’d be surprised if it was. If anything I have to imagine cyber bullying makes it worse.
