Reddit, this is unacceptable! What do I do?

I'll start off by saying that I'm Jewish so it explains why I'm mad about this whole situation, please read as I have no idea what to do:

My dad's friend has a son that goes to a public school (12 year old and also Jewish). They had to do a project about someone they strive to be. One of the students did his project on Hitler and (according to the Jewish kid) mentioned that his "killing spree was an accomplishment". Another student decided to do his project on Bin Laden and was also quite insulting to both Jews and Americans. The kid said that the teacher SAID ABSOLUTELY NOTHING and instead congratulated them on a job well done.

I find this absolutely ridiculous and disgusting. This is no joking matter, and I have no idea what to do. I always let things go, this time, fuck it. What can I do? that teacher deserves to be fired.

/e Also forgot to mention that the kid refuses to go to class now and his dad is already searching for a new school...
