Well not to beat a dead horse but I saw similar behavior years before there was a feminist movement. This isn’t atypical in some parts of latino culture. It’s not WASP society.
Don’t worry, it’ll happen again because these women are teachers and because they strongly believe in their “right to sexual freedom” they think that what they’re doing serves a purpose and that they can change the way American society views the norms of human sexuality. In Sweden, there is a movement to legalize incest and necrophilia and many of those activists are young women too. Somehow, they got it into their heads that it’s time for such radical changes but they have been horribly misinformed.
