Harsh people who reprimand others, do so, not because they are standing for justice, rather they have been reprimanded, hence their self-esteem has been shattered; coupled with that, they fear others (as, just as they were harshly criticized, they are always acting in a manner to prevent such criticism, hence their lives are, quite literally like walking through a minefield, which creates jealousy of those whose lives are calm) hence they harshly criticize, not to elevate, but to destroy others self-esteem, and the proof is, that they choose to harshly criticize Jews, Americans, the kindest; not say Syrians, Islamic jihadists, the cruelest.
