“are you mo”
I do accept that characterization of MO although the distinction between me and a charedi orthodox Jew has to do with my acceptance of science, history and secular culture rather than any differences in mitzvot observance. I have not personally identified as OO even though I agree with a few things that are done in that name (like semicha for women).
“i thought yeshivish girls dont learn gemara?”
I think you are correct and today that may be the distinction between the two. It should be pointed out though that Rav Soloveitchik z’tz’l was at one point a member of the Moetzet Gedolei HaTorah of Agudath Israel of America.
