I wouldn't call this child abuse, they aren't in any way directly harming the children.

Also, are they making any direct calls for violence? Maybe it's just me but I want to live in a world where people are allowed to hate other people. Stay out of my head please.

And sure, people will say, stay out of these childrens' heads. But they are minors, parents and institutions have a right to teach them. I bet a few hundred years ago they could have argued it is child abuse to make a child believe they live in a godless universe.

If you won't support free speech all the time then don't get upset when you find yourself deprived of it.
