If the dude is actually a pedophile he has a mental illness and needs to come to terms with that and get help. I don't think anyone wants to be a pedophile. Of course that doesn't change how dangerous it can be, or how repulsive it is.

In that case he should shut the fuck up about finding highschool girls hot, and get professional help from a psychologist or something so he never acts on it.

Him dating a very young woman is very weird, but as long as she's of legal age and consenting it is what it is.

I agree that some people are too dangerous for society. Keem could be, but that's for a professional to say. We don't really know any of these online personalities, concerning comments and dating a very young but legal woman isn't enough to put him in handcuffs or say if he's a real danger.
