Ok, but do you think those 12 year olds are going to all grow up to be well behaving adults? Or maybe the problems with this kind of sexism are starting very young. If you are right then the solutions still need to be addressed, but we need to start earlier.
Do you remember how sexist were the 70's and the 80's? People who were 12 back then turned out just fine, considering that we're even discussing this, didn't they?
One big difference is that there was no access to the sort of degrading pornography that is just freely available today. A 12 year old boy in the 70s might be able to get his hands on a Playboy or maybe even a Hustler but it took some real effort and those magazines were tame compared to the porn today.
