More than once when I was young, I was old I was “pretty for Jewish girl.”
The couple of times my parents overheard, they told me it was meaningless. They didn’t tell me I was as pretty as anyone, nor discuss anti-Semitism. They basically just let me know that the content didn’t matter, and someone else’s opinion on what I looked like could safely be ignored.
I’m amazed at how right they got things, sometimes.
