Rav baruch ber wrote when quoting rav chaim brisker, “ve’amar kadosh yisroel” in the middle of a piece, not just as an introductory praise… This is how he looked at the gadol hador.
As for MO deciding that praising gedolim or listening to them blindly, as the torah says to do “lo sasur min hadavar…” Even if they tell you left is right and right is left…, is somehow linked to idolatry… It only shows how far their own ideology has taken them away from basic yiddishkeit.
And an MO response to lo sasur is that it’s only halachikally binding when it’s a beis din smuchim… the obvious answe to this, is that according to them, it’s not idolatry when it’s a beis din, but it is when it’s the gedolei hador?
They just have a problem with authority. And should you think that it’s only rabbinic authority they don’t like… Google “struggling with God modern orthodoxy” and you’ll see it’s authority of the Almighty that they aren’t fans of either.
