zen3344: In one of novels, it turns out one of Spock’s human ancestors (meaning on his mother’s side) is Jewish – remember that since most non-Jews marry goyim, having a Jewish surname is “proof” that one isn’t Jewish. By that novel’s theory, Spock would be Jewish.
The original series presented the Vulcans as being very “Jewish” (his was in part Leonard Nimoy’s doing), with (from a Hollywood perspective) super-nerdiness, bizarre customs and extreme commitment to academia.
