Are you really suggesting that 13-15 year old males aren't actively engaging with gender roles, either through experimentation, modelling, or complete internalization of roles and expectations?
The world is changing pretty rapidly overall, and gender roles are no exception in this country. There are some challenges that creates, and unfortunately one of the results is a subgroup of men that react to a loss of privilege by becoming even more aggressive. I'm sure some of this plays a role in most of these idiot kids doing incredibly dumb crap. Yes, a lack of parental supervision, too much free time, too great a feeling of anonymity, and a healthy dose of narcissism play into it all, but toxic responses to internalizing gender roles often plays a part.
