"Why do guys have all these anime girl pics pasted everywhere? We didn't do that in my day!"
I actually hear - and once said - this out of ignorance, too. It's a side effect of being raised in the feminist society where every space is intramural, there's no area where boys are able to make their own clubhouse and put hot women on the walls. When you realize that kids are increasingly so hyper segregated from each other they've accidentally re-created the boys' lounge of old, you'll find we're just doing the same thing our grandfathers did.
