I showed this video to my grade eights We are studying Aztecs. Lots of blood sacrifice correlations to who they thought were the true Gods. Wish I could teach that in class..
Yes, in that sense it must be hard to be a teacher. We know that much of what we teach is not true, or a twist of the truth. In the past, critical thinking was part of the education, but I think they've taken that away--it's no longer necessary LOL.
