@Miller,
My insight to a "Gentile culture" existing is that I am using that word euphemistically to refer to what was once Catholic Europe. Interestingly enough, non-whites, non Catholics, in my opinion, have adopted the mindset of the prejudices of what was once the dominant culture in Europe (Catholic), meaning Jews can still be persona non grata in genteel or other circles.
Have you noticed how in urban neighborhoods that have some diversity, non whites (excluding Blacks) want to live in what was once nearly a totally white neighborhood? Why? I suspect that the dirty little secret is that for a non white, of non European descent, living in a neighborhood that was once totally white, and therefore is still considered white, is their version of ALIYAH. Get it
