Should I withdraw my son from the school.?

I was having my annual 1 hour talk with my son that I have every day at 7pm before he goes to bed.Anyway during the chat we had moved onto history of America. I asked him to list all the American presidents. I was shocked to find out that he missed two of them, Chester A. Arthur and Benjamin Harrison. I was shocked. He had forgotten two republican presidents.I am afraid they are teaching my poor Edward left winged ideas that I will not torte. My family and tradition is very right winged and I will be god dammed if my son is going to end up like Kennedy or Clinton the maniacs! Do you think the school is teaching him to be left winged and what action should I make sure he never becomes a lefted wing maniac? I yelled at my son for having these left winged polices and he simply sat there listening to me, not saying a word. I now spend more time with him hunting and teaching him that to be left is bad. He insists he is right winged but I'm not sure. Should I remove him from the school?
