Some additional two cents, based on my dealings with teens today.
First, try to consider whether or not this is just edgy behavior or actual malice. If it’s the later, avoid the temptation to come down too hard too fast. Having it turn into a massive incident isn’t going to do anything other than feed into whatever nascent Antisemitism is there. Getting the kid suspended is likely to make him think, “See! I was right! That cowardly Jew kvetched and got me in trouble!”
I think there’s a good chance this isn’t actual antisemitism. A lot of teens tell me that they’re tired of the brainwashing at school about the Holocaust being THEIR fault because they’re white. It’s absurd, white American children have no collective guilt over an event that happened over 3 generations ago.
A lot of these kids realize they’re being manipulated and they lash out. They’re being demonized as being Nazis for existing and some are choosing to embrace it rather than let themselves be made to feel ashamed for something they had no part in.
I know it’s not easy for you and your daughter, but she very well could just be caught in the crossfire of this insane culture war we’re stuck in the middle of. Or maybe he just thinks your daughter’s cute and is awkward.
“Getting the kid suspended is likely to make him think, “See! I was right! That cowardly Jew kvetched and got me in trouble!””
Talking to the school never crossed my mind, nor the father’s CO, nor anything involving the law.
It’s dad-to-dad or nothing.
