n0mesora: Neither of your “easy points” are necessarily true. The only big community in the entire south is Miami, which is probably cancelled out and then some by Chicago. The second largest community in the south would be dwarfed by Cleveland. That statistic is just observably untrue. And this is all without even considering that the midwest would actually have a sizable non-Orthodox population, whereas I doubt the south does given that most liberal Jews are irrationally terrified of southerners.
“If someone is part of an Orthodox Shul and drives on Shabbos to eat in a Burger KIng, then for the purposes of this survey he is Orthodox.”
We get that. We’re saying that makes it a pretty useless or at least flawed survey.
