Anyways, as with the 2a stuff. I'm going to bow out. Admittedly I don't have the answer, I don't even know the questions.
I haven't spent time in NYC much in the last 10 years so I am clueless.
I do know that it's all prospective, I had a Lyft driver in Raleigh NC, African American young lady rail about racism in the area and the next day a middle aged African American male Lyft driver said she's full of crap it's really how you act (insert Chris rock how to not get beaten by the police)
Others have theorised that the reason we see this in NYC is due to close living. Tensions run high and Jews are insular generally .
I made a couple of guesses, *shrugs* I'll go crawl back into my hole
I edited my comments accordingly to at least try to stay on focus, sorry to veer off, I have really bad ADD.
