less: Chinatown is outside BP. It starts at about 10th Ave, where Jewish BP essentially ends. Neighborhoods aren’t defined by technical boundries (in fact legally there are no exact boundaries for NYC neighborhoods) but rather by similar neighbors. Neighborhood boundries are constantly shifting. And Jewish BP has expanded further and further out (on all four sides) for many years. The core of BP is almost entirely frum. (Roughly speaking between 11th and 21st & between 39th and 60th. Though many blocks outside that area are heavily frum too.)
DY: Thank you for making a point to point that out as often as you do, including where there was no expressed agreement or mention of the same points. Your point is well taken. Great authors are recognized by their literary works even without attribution.
yosef9: If you put an ad out for your basement apartment for rent that exluded an ethnic group you’d be in legal trouble even if you tried explaining that you simply couldn’t live with folks of that ethnicity or race. Nevertheless, I sympathize and agree with your second to last comment above not wanting to live with that specific group. Where we part company is when you carry over that feeling to frum Jews, whether it is not wanting to live near too many Sefardim or near too many Yekkes (cause you’re not a Yekke), etc. You should be comfortable living near and with any type of frum Jews.
