Question

Earlier, in some thread with the Rabbi, a question came up about rabbis [who are apparently experts in questions like clipping toenails and the like] whose way and public educational and moral conduct causes people to feel disgust at their behavior, to the point that they cry out: “Woe to his father, woe to his rabbi who taught him Torah; look at his ways and deeds, how ugly, contemptible, and low they are.”
It should be qualified that of course not all rabbis are like this.
For fairness’s sake, I’ll note that I feel this way too—to the point that when I was invited to take part in a significant Torah project, I could barely restrain myself from telling that rabbi to his face how much I “appreciate” his opinions and actions, and that in my view the crooked Torah outlook of him and his colleagues brought him to such lowness…
And with such a miserable, low, degrading Torah, I’m not prepared to be a partner.
God surely did not give that at Sinai. 
Now to my question:
Is the desecration of God’s name [which even Yom Kippur, repentance, and suffering do not atone for, as it says, “Surely this iniquity shall not be atoned for you until you die”…] dependent only on those rabbis and on how upright people see their moral and ethical decay? And in that case the sin is only on them?
Or also on
the one who says so? [Even though he feels that this is the truth at the moment, and looks honestly at upright people who did not study like those rabbis, and at those rabbis, and the comparison cries out from one end of the world to the other…]
Or on both?
 
And is there really a prohibition against thinking fair, upright, and truthful thoughts about the world, and about who is good and upright and who is corrupt and corrupting?
