The Richmond Hill area is the only area in NYC that has a substantial Punjabi population. It is not known to be a dangerous place.
Punjabis move there for the same reasons they move to areas with relatively large populations in the UK (or Canada, or any other country).
If a person has a platform and the power, it's a necessity. But even this late in the game I think it's too late. Should've been kicking up a fuss or at least having serious discussions about "Behave / Reform or Deport" about 10-15 years ago. With the media having completely abandoned the pretence of partiality and maturity in the past 4 years, they're in full defence mode now, and will likely get worse.
