Why are there so many jews in lisp?

I'm used to jews being in all the subversive parts of society (banking, leftist politics, etc.) but CLISP and Scheme both seem really nice to me, especially Scheme. However McCarthy was a Jew, Sussman was, Abelson was, CLISP boots to a fucking menorah, and some popular schemes are jewish (Winkelmann's CHICKEN-Scheme comes to mind).

What the fuck is going on?
