Why would a racist care for anyone of a race they despise and vilify? Being a child has nothing to do with it. Children become adults and soak up the values around them; so if they hate the adults, of course they hate the children. Why would they want their perceived enemies to be safe and have basic education? That just gives them more resources to fight for revindication, which is a threat to the ones who hate them in the first place.

None of that is right, but it’s not difficult to understand either. Don’t try to find some complex logic behind it, the reasoning is incredibly basic.
