Oh, I'm well aware I'm from there. NYC is as segregated as they come. Right now a rising problem in NY is going on in Brooklyn between the ADOS and Caribbean-American residents of the neighborhoods and Hassidic Jews. Jews are reporting attacks and robberies while they are being blamed for trying to price out residents/gentrification and general slum lord practices refusing to repair tenants units, and in places like Crown Heights living in the community but in isolation and not distributing wealth.
However, LA seems to be on another level in terms of how territorial/divided it is and watching the movie for me further reinforced that, and the whole gangbanging politics muddies shyt up even more. I also think LA is a lot more spread out which leads to more division.
I guess it's just a matter of perspective, fam. I would say LA is Top 10, but Top 5 would be pushing it for me. There is racial tolerance in LA, particularly in parts of the more integrated parts of the Westside and Central LA. Obviously LA has 4 million people, so we're not just talking about a handful of people on these other sides; there are areas you can be in Los Angeles and you have a blissful ignorance of the intolerance and segregation and racism in other parts of the city, same as it is anywhere (to use a less known example, I've seen this same dynamic in little old Fayetteville, NC. This type of thing is common in many areas of the country)...
I've seen too many places that have serious racial issues themselves, with even greater social issues, to consider LA the worst, but I'm not denying that it is among the worst. But I guess my point is, I don't really fault your perspective. Mine, I just think LA is not quite as bad as the outer public believes...
I guess a better question, or a better statement to make, is the entire United States has a harsh legacy of racism for people of The Diaspora. So it would probably be easier to identify the handful of places where there is relatively high tolerance and integration for blacks. There is no perfect place for blacks in the United States, most places are dealing with variations of the same problems, so who we think is "worse" at some point is really subjective to what we decide to accept about a particular place's issues, compared to the place we think is "worse"...
I don't think anybody would necessarily say New York by itself is a beacon of racial harmony, as you alluded to yourself. But when people line it next to Los Angeles, there seems to be a public perception that New York is better, which really isn't founded when you look at the history of racism against blacks in NY, so it kinda speaks to a perception that people view NY's issues as easier to accept than LA's, even if in reality, the two cities have similar histories and rates of discrimination versus blacks...
I'm just using NY as an example as it's a prominent city, I hope what I'm illustrating makes sense!
