Burnt Steak:
As stated on their web site, OJ is not “MO”, even if they attract a variety of students.
From their site: “Yeshivat Ohr Yerushalayim is unaffiliated politically or philosophically with any political parties or formal religious movements. Its goal is to emphasize the primacy of high level Torah study and love of Klal Yisrael and Eretz Yisrael.”
The last line, however, does, at first glance, seem to neatly align with MO’s “Am Yisrael, Torat Yisrael and Eretz Yisrael”, which probably makes it attractive to MO.
Looking at it more closely, however, they note (in English) “limud haTorah”, not “Torat Yisrael”, and “Klal Yisrael” rather than “Am Yisrael”. Those particular word choices imply Torah-true orthodoxy, not “MO”. But it’s probably still “kosher” for “MO”, too.
