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.
Even in more progressive areas boys are socialized differently. I’ve been in a field where I see early childhood until middle school for years now. And girls, from the beginning, and raised more strictly. They have more care in their clothes, their meals, and the skills they are taught. They rarely fight, and if they do, it’s not on impulse. My theory on why people often say “boys are easier” is because they absolutely neglect them. So the onus is on 3rd parties to often teach them basic skills and rule following, to control their impulses, etc. Even in K-5, boys are the ones who are telling their teachers to fuck off, leaving the buildings without permission, fighting, etc. Parents blame the teacher/staff, if they are present at all, and antisocial behavior gets rewarded again and again.
