Yeah, that's why you monitor what the kids you're responsible for are doing on the internet. It's trivial to setup parental controls on a network.

Hell naw, that's an arbitrary take. There's no "child things" or "adult things", nor "male things" or "female things", just things, and the "male"/"female"/"child"/"adult" is an arbitary tag we put on them.

And even if there are some things that aren't so good for the child to see, the only correct way to address that is educating them, guiding them, listening to them and, over all, treating them as humans, the "we need to block this to children" is totally adultist.

Maybe, but that doesn't matter since automated age verification doesn't work. Kids always figure out ways to bypass it, and it snares unlucky adults all the time.
