He didn’t leave his teaching job.

I don’t necessarily disagree with you. But it also doesn’t magically make you a sexual predator either. We have rules to prevent sexual predation, such as that you can’t fuck your students and someone has to be over a certain age to have sex with an adult. From my view this is all panty wringing and the dude broke no laws. Maybe he is a predator, maybe the laws should be changed. Or maybe we shouldn’t infantilize sexually active mature human beings and maybe we ought to teach our daughters about dudes like this.
