Wolf, specifically regarding that position, Rav Elyashev stated that while that position is apikorsus, the subscriber of that position is not necessarily personally an apikorus. If I recall correctly I think his reason was because the subscriber mistakenly, but sincerely, thinks its a halachicly legitimate position to hold.
So, you’re going to weasel out of it by saying that as long as the apikorus beleives his apikorsus, then all is well as we can welcome him? I don’t believe that normative halacha views the matter that way.
