Tuna – criticism of gedolei yisroel from chabad usually just boils down to “sinas chinam,” “why are you soool against chabad, look at all the great things we do(for the sake of our rebbe), or completely fabricated stories about rav shach.
Criticism of neo chabad is just reading the statements of their rabbis and their rebbe and showing how against the Torah it is. Because it’s criticism, not emotional defense mechanisms protecting one’s self from the blithering truth that the “nasi hador” was hardly accepted as such outside of crown heights.
