adorable, I think everyone agrees that OOT’S are more accepting. A Jew is a Jew.
I think in NY communities like BP, the Chassidishe people feel their background and Derech is superior to others, while in Flatbush its the Litvishe, because they are the majority. Those who are from the background with greater numbers, feel superior to others who are in the minority. I think part of it is wanting to pass on to their children that what they are is the best, to prevent the children from swaying in other directions. If parents send vibes that we’re all equal and G-d loves us all equally, then why shouldnt children pick and choose which Derech they prefer?
With certain groups its not only what you are now, thats of great importance, its where you’re from, despite many great BT’s and Gerim in our history.
