This video shows an interesting contrast, however the problems aren’t caused by “diversity,” but rather they are caused by the Freemasons intentionally engineering it to be that way by strategically importing the most violent and incompatible people as possible.
When I lived in New York City in the 1990’s and early 2000’s, it was amazingly peaceful and safe, no matter where you went or what time of the night you went there, including even in the most remote parts of Brooklyn and Queens. Being accosted or harmed was not even something that I was concerned about, and it never happened to me in all those years.
Riding in the subway in NYC was almost always peaceful and tranquil such as the example this video shows in Poland.
Also I remember a scene in the movie “Eyes Wide Shut” where the character was accosted by a group of people on the street in the East (or West?) Village in Manhattan, however the odds of that happening at that time were really less than being struck by lightning. Even in Brooklyn and Queens it would have been almost unheard of.
New York apparently had a lot of crime in the decade before I was there, however.
