Charlie,
” Nobody with any knowledge about Rabbi Weiss, even those who oppose his innovations, thinks that he has said or done anything that would put him outside the halachic bounds”
This is completely untrue. Thise who know exactly what he has done and have not partaken of the koolaid that Weiss serves say exactly that, that his apikorsus places him outside the realm of being kosher for eidus (and eidut as well) for those who follow halacha.
