Bringing up their family history, while not actually naming them is uncomfortably close to some hitlerite shite, comrade. You're inadvertantly tying being Jewish with zionism. I hope not capitalizing Jewish was a mistake.

Also, wikipedias list of (incomplete) Jewish jazz musicians is 129 pages long, and doesnt list what they excell at / mainly play. There's heaps of Jews in jazz, the nazis included it as redacted art.

I'm not trying to suggest anything about you, this is just how it reads to me. If someone's a genocidal fan, just name them.
