It's not boys will be boys anymore. It's keep them drugged and controllable so they don't do anything useful but drool. It's all about government control of the masses through oppression of producers and providers of the family.
They start early, too. Sadly, I've seen this in the way some relatives treat my son -- he's the only male child in a family with seven female cousins, and the complaints about how "noisy and agressive" he is -- just doing "boy-things," like playing with Tonka trucks -- are ridiculous.
