There is a good Daria episode that explores this situation (despite they take the SJW route on it a bit). One of the students requests a model agency to go to their schools to try and recruit models. Daria and Jane are, of course, against this and Jodie asks them why they always have to be contrarian, people should be free to do whatever they want, right?
Jodie: "If a kid wants to take a modelling class, you can't tell them no."
Daria: "Maybe not, but you don't have to let the fashion mob push the classes on school grounds, either."
Jane: "Yeah, it's not fair to the drug dealers. They have to wait behind the parking lot."
Jodie: "It's completely voluntary. What's the problem?"
Daria: "No problem. But why stop at modelling? Maybe there's a go-go bar downtown that would like to come here and recruit lap dancers."
We are already on the stage of schools allowing people who dress as women to perform suggestively entering schools. What's next? Actual prostitutes? That's kinda of the point, the slippery-slope that people keep saying it would never happen. Well, it's happening. We're now allowing kids to enter a world that is about sex and drugs. The only defense people like Wendilou have is "well, my kid doesn't do that!". Like I said before, we soon will take girls to an actual brothel, let them watch prostitutes be with clients, and say "well, the kids aren't actually the ones doing sex, right?", after all "sex worker is like any other job". Yes, I get that nobody gets to decide what kids should NOT do, but then, who gets to decide what they SHOULD do?
ETA: spelling/grammar.
