But, as official material, you have to realize there is a chance of a teenager presenting this to a pre-teen. Do you honestly trust them with that?
I trust them with it more than I trust someone else to decide what they should be trusted with.
Would they handle the subject matter in a way that would be useful and good?
I don't know. Maybe not. But you know what? That is a good reason for us to consider, perhaps, having the material
with guidance on how it should or shouldn't be used, rather than leaving them to invent it for themselves (which I assure you they'll do anyway) and not have that guidance.
A game is going to have people reacting based on shallow and fast thoughts, not the types of things that could benefit anyone.
I don't even know what you're going for here. Games might have people reacting that way, but what makes you so sure that shallow and fast thoughts are "not the types of things that could benefit anyone"? What are your qualifications, exactly, to be an authority on what
could benefit
anyone, as opposed to what you think most likely to benefit the people you think are most likely to be playing?
I don't think the evidence is there to support this idea that the way people respond to issues like that would be "noot the types of things that could benefit anyone".
I've never once said "this content should never exist anywhere ever". That's just what people are putting on me, because I've said "this content shouldn't exist in official DnD materials". Those two things are VASTLY different.
I've been watching moral panics come and go for a very long time. in practice, no matter what you
personally intend, the
entirely predictable outcome of advocating such policies is, in fact, sort of bad.
I don't think "absolutely cannot occur in official materials" is a good stance. "Shouldn't occur all over the place" might be pretty good. "Should only occur in official materials that have some kind of age/suitability warning" seems like a good idea, because we want people to be able to make informed choices. But I don't think keeping things out of official materials really solves the problems you want to solve, and I think it could enable problems we should be very wary about.
As a parent, I am all for making it easy for people considering getting things for their kids to vet the material and understand what they're getting into. But honestly, I trust people who don't think that's important more than I trust people who make sweeping proclamations about what "could benefit anyone".
