1) The way to tell if a movement is Orthodox is simply whether they follow Shulchan Oruch and the Rambam’s Thirteen Articles of Faith.
2) Rav Bamberger, the godol hador at the time of Rav Hirsch, was against the Austrit (secession movement), and felt there was nothing wrong with having a unified kehillah along with the Reform.
3) I don’t know which movement is more anti-zionist, Lakewood or YCT. Instead of debating why not become comrades in arms.
