Wow, tip of the cat's hat to you for being such a great teacher (no sarcasm). In today's political environment, you are being brave.
With the world so on edge - akin to the 1930s - people particularly in the US want desperately for choices to be black and white. Everything is so hard right now for average people; they want decisions about who is bad and good to be easy.
Noone is all good or all bad. Every hero has feet of clay. Mother Theresa had some VERY bad traits, FFS. Teaching kids to recognize nuance is great. Teaching kids that each of them can decide on their own what is right and wrong is even greater. Good work and good luck!
