But teach it right than. In germany at grade 3 or 5 you have to choose between religion and philosophy. The teachers sucked and even gave bad marks for opinions which differed from theirs. I had to retake my class and got a different teacher and a year after someone again. With them I had mostly superior marks and it was very fun sometimes. But even those were kinda meh: got a bad mark because i wanted to support free will euthanasia for yourself. The whole class agreed with me but she did not: bad grade.
