My parents did this! They explained that most people are brainwashed/radicalized but still good people and still deserve respect. And that you have to play the game to advance in society. It's ok to know more and keep it to yourself in most settings. 

 It's gonna be tough. Encountered a 9/11 reference in a kid magazine tonight. I tried stuck to the bare facts and said "I'm sure we'll talk about this a lot more as you get older..."

 Sorry, I am not clear on the emoji meanings here  

 And that will be difficult days, talk about it with your son. This was a very sad event! 

 A hard lesson 🙏
