I’m getting vibes from the article that Rav Adlerstein and many other “right-wing YU”-type RCA rabbis (btw I am aware that Rav Adlerstein didn’t go to YU) want to make a splinter organization if the RCA doesn’t take a stand on its Orthodoxy.
I don’t see that in the article from R. Adlerstein or as being realistic in any event. If they want to be right-wing-types they can simply be Chareidi. There really isn’t any room for a something more right-wing than the RCA but less right-wing than Chareidi.
