ZSK: “The proper term for those communities is “Edot HaMizrach”, although “Sephardic” seems to be the adopted term”
Which communities? How are you differentiating between who is properly Sephardic and who is properly Edot Hamizrach.
Specifically describe each and how you properly differentiate between the two.
(And where “Northwest of Manhattan”? That sounds like some upper scale Modern Orthodox wannabe community.)
