i don't recall zipperlip stating he fills their heads with rightie nonsense, if you read his comment he says he gives them the choice
maybe you are referring to the part where he tells his kids how to respond to clearly biased teachers in the event they bring it up again
so you are going to play the "not as bad card", interesting choice, yes shooting someone in the head is not as bad as torturing them to death, right? so it's fine then?
there is a clear issue with the scenario presented, there isn't a need for but thats worse than this clap trap
