The whole taxonomy is off. There are plenty of people who carve out their own paths, and who affiliate and borrow from with different sectors and communities and approaches.
I know lots of people who are clean-shaven, own a television, daven Nusah Sefard, and wear a bekeshe on shabbat (I even own a bekeshe that I’d wear on shabbos in the past), and others who combine elements of Modern Orthodoxy and Open Orthodoxy with a classic Sephardic approach and even elements of German Neo-Orthodoxy (I’d definitely fall into that camp, and a friend from Silver Spring would, as well).
I happen to work as a hazzan in a shul where they have a potted plant mehitza that is a little more than 10 tefahim high. This was a synagogue that was staunchly non-egalitarian Conservadox with a YU-trained rabbi for many years. Upon his retirement, it was told to me that the shul board voted to instate separate seating, a bima/shulhan facing the proper direction, and to eliminate the microphone. The shul has one YU-trained rabbi and another rabbi with the semikha of R’ David Weiss HaLivni. The mehitza is not ideal, but its presence at least makes the shul a viable option for halakhic Jews to visit and daven in. Without this arrangement, I would not have accepted a position there.
YCT did have a mehitza-only policy, but I do know that one of their graduates is now the rabbi of a synagogue in Overland Park, Kansas where they have no mehitza (and where the UTJ rabbi of the shul I work at once completed an internship). I don’t perceive a tayna “against” the mehitza among the progressive Orthodox, but I do feel that those in this camp are intellectually honest on the topic, as indicated by my many postings on the issue.
