Dude... you're not helping your cause.

Sometimes fundamentalist Christians say the dumbest things. Sometimes they don't. And sometimes they hold up signs saying the dumbest things:

I know this guy is trying to make Satan look bad, but he's doing a horrible job at it.

With the exception of witchcraft, which is just another religious belief that can be as irrational as fundamentalist Christianity, none of those things are bad to learn about and should be taught to all children, with the exception of sexuality which should probably be taught to a teenager rather than a child as a child would probably be to young to understand and might even get a bit freaked out by some of the thing you're talking about.

There is nothing wrong with teaching a kid about evolution either as evolution is science and all children should learn about science of all types, even ones that certain highly religious do not believe in.

As for psychology I can't imagine why even fundamentalist Christian would want a child to not learn about how the mind works, unless they are a fundamentalist Christian that thinks that all psychological issues are the result of demonic possession.

Regardless, this guy is not helping his cause. He's hurting it... badly.
