It has nothing to do with “putting people down” nor is it doing anything of the sort. Having a discussion on what is right and wrong has everything to do with Kol Yisrael areivim ze lazeh. Whether the discussion concerns hotels, shaitel, vacations, hechsheirim, college, tefilin, concert, rallies, or hat and jackets. Whereas there IS a Torah viewpoint on all these issues, there is every reason to be concerned for each and every Jew. One for another.
And that is the point.
