This is irrelevant to the point of absurdity. Even if you are correct, and it would be an impressive feat if this were true in the flagship institution of Torah Umada, the discussion is about the institution and movement, not the frum kids at YU who manage to ignore that particular kefirah.
To the point, again, the reason that there, unfortunately, has to be a distinction between MO and traditional observant Judaism is that MO is not only Judaism but rather a merging of Judaism with other outside influences like secular nationalism and various other ideas.
To take one (major) example:
We’ve discussed many times that the gedolim held Zionism to be A”Z and kefirah. We are also quite clear that MO is proudly Zionist, to the point that Zionism is one of the major tenets of their faith, also as discussed. Put the two together and you get…a big problem.
Read what Rav Shach and others wrote about the founder of MO and about the founder of RZ, certain successors to the above, and about MO and RZ in general.
Again, I’m sure you’re wonderful people, but the facts are what they are, as our gedolim indicated clearly, that these are deviant movements.
