rabbis who want to dominate their students

Maharik (12:62) There are some rabbis who want to dominate their students more than is appropriate and they assert that whoever has been a student even as a child is forever subordinate to them and can never disagree with them on any issue. They claim that this is true even if the student has become their equal or even their superior in learning because they assert that even if the rabbi has clearly erred or behaves incorrectly, that disagreeing with the rabbi is the same as contradicting G-d or other such claims. The answer to this is that even if the student is forever subordinate to his teacher as the rabbis assert, nevertheless it is quite obvious that this is only in relationship to honoring him by standing up for him. However, concerning matters of Heaven, eg. Chillul Hashem, there is no requirement to honor his teacher. This can readily be seen in the many examples in the Gemara such as the events with Rabban Gamliel (Berachos 26b)
