I really don’t see feminism feeding this. I’ve known a lot of them (feminists) over the years and unless there has been a radical change this isn’t their sort of issue.
I suspect it’s more a cultural issue. People tend to believe that latino culture is heavily Catholic but in reality there’s a whole lot of sexual looseness as well. I think this is just hedonism plus opportunity. Probably a physically mature kid for his age and a teacher who found him attractive. She’s used to doing exactly what she wants and little things like social mores are insignificant. Until she got caught.
It’s feminist activism because they don’t see themselves at all as being easy or as being sluts. It’s young women doing what they’re doing “because they can” and it’s feminism that tells them that they can. It’s empowering and that’s why feminism is attractive to them.
