By today's standards? Yeah, it probably is. I don't even care anymore though. Homogenous societies have fewer problems of inequality, less crime, more social cohesion. We've known this since Aristotle in Greece, since Marcus Aurelias in Rome, and probably with some other writers I can't think of in between then and now.
It's not a statement of any one group being better than another.
It's not a statement that I don't enjoy many aspects of our diverse society.
Any divide you wish to draw, I'm not drawing them. SF is more diverse than Krakow when you account for race, place of birth, religion, sexuality/gender identity.
>And what attribute are you declaring causes a 'lack of homogeny'?
