I started out by saying I knew nothing about the Linn LP12, let alone its founders religion or culture.
I did a little research and can’t find your reference to racism towards Linn, although i am sure it is there. I did find that Ivor was Jewish. His family fled from Austria to Scotland in 1939 (I can only imagine).
Antisemitism is real and wrong on so many levels. But IMHO I have to agree with Lewm when he said “I think it is a reach to connect LP12 criticism with anti-semitism. There's enough of the real thing going around already.”
Regardless, my apologies for making light of something that is real to you and others.
