In my previous post, I divided Orthodoxy into 6 groups. As Hedyot pointed out, and as I realized about 5 mins after posting, there is another huge differential that I didnt point out. I shall call it the Serious / Faker divide. In each group, there is a split between the Serious guys and the Fakers. Here I shall explain:
RW-UO
Serious - very, very frum indeed. The genuine article. Listens to the Gedolim without question. Would never chas vesholom do anythign cneged the gedolim, chas vesholom. Thing genuine kollel guy in bnei brak who really learns.Faker - Born into it but doesn't really believe. Maybe goes to minyan, but shmoozes at the back of shul. Very unhappy with his lot, but won't generally amit it. Think Hasid and A Heretic.
Centrist UO
Serious - Learns a lot. Very frum. Typical good Lakewood guy.Faker - Goes with the flow. Spent some years in yeshivah but was a batlan. Goes to minyan mostly but gabbles it off quick. Will hang out in sports bars and do other questionable activities, especially on vacation.
LW UO
Serious - Frum but wordly. Learnt in a good UO yeshivah eg Ner Israel, even the Mir, but also has a college degree. Is probably a professional. Charedi but normal.
Faker - Goes with the flow. Not too into charedisim, but spouse / parents / children / community means he just tags along. Not much difference between LW UO Faker and Centrist UO Faker.
RW MO
Serious: Very frum indeed. Learns a lot. Semicha program at YU. As frum as a Serious LW UO. Probably not as frum as a Serious RW UO. Comparisons to a serious Centrist UO are interesting and highly debatable / tedious. Think Top YU guy vs Top Lakewood Guy.Faker: Doesn't really exist IMHO. If you are not into it, there is very little pressure to be here.
Centrist MO
Serious: Does daf hayomi. Attends shiurim. Learns a lot but is also a professional and worldly. A fan of RYBS.Faker: Goes with the flow. Possibly Orthoprax though might not realize it. Goes to shul shabbos mornings. Keeps kosher and shabbos. Doesn't learn. Attends an Orthodox Synagogue but not much more.
LW MO
Serious: Reads Shapiro, Halivni and similar writers. Founded an egalitarian minyan on the UWS of Manhattan. Wants to redefine Orthodoxy.Faker: Similar to Centrist MO Faker. Is nominally orthodox and wants to stay that way, but couldn't really explain why. Goes to shul occasionally
