You do realize that what it says in Yeshurun seems to be largely based on conjecture, right? Doesn't necessarily make it wrong, just to point out what large swaths of his argument seem to be based on.
He’s basically saying that they are unaware of the respect according numerous times, and absurdly tampered with this one because they couldn’t stomach it.
The chassidim are unaware of the respect granted numerous times in the sefer, and "absurdly" couldn't stomach this one instance? Perhaps what's absurd here is the claim he's making...
