“You can’t accuse someone of being disingenuous and then expect to promote your opinion by quoting his. V’hamaynin yovin.”
It was the opposite – He was attempting to prove that someone was being disingenuous and part of his proof (whether valid or not) was via quoting his opinion. (Sorry for all the pronouns but I don’t want this post to get deleted.)
“Kol haposel b’mumo posel, so you can’t expect Antone to take him seriously as a posek. Again, v’hamayvin yovin.”
I will have to confess to not being a meivin – I don’t get your point. If a posek accuses another posek of an improper psak then that make the first posek not a posek?
“it’s more than just an issue of disrespect, it’s really, although he would deny it, almost complete nullification”
It might be a nullification of the psak but it is not a nullification of the person. Same as the Rishonim and Acharonim.
“there’s a certain hierarchy in Klal Yisroel (earned), and you can’t compare one person or situation to another. This fellow isn’t in the same league.”
This point I actually agree with somewhat.
