HIE, I think R’ Reisman would be the first person to tell you that WolfishMusings (and others) are allowed to disagree with him.
Disagreeing with someone doesn’t mean the person has no respect for that person, in practice it usually means the person does respect the person. A person you don’t respect, you don’t disagree with, you ignore.
Furthermore, whenever I have had discussions with my rav and I disagreed with him and argued with him, he never once told me I’m gonna burn, he enjoyed it. It allowed him to clarify his position, and once even change his position to more match my argument.
Someone who is afraid of being disagreed with (and here I’m talking about halacha, kal v’chomer and eitza) is not a gadol. You won’t find one rav/gadol who won’t argue with you a piece of logic he spoke about. What do you think happens after a shiur/shmooze when people crowd the speaker? They’re arguing, debating, clarifying positions. That is the beauty of Judaism. We don’t have a Pope spouting stuff, we have people learning together and clarifying positions and halachas.
