15 The best way to dominate and gain control over people is to spread despair and discouragement, even under the guise of defending certain values. Today, in many countries, hyperbole, extremism and polarization have become political tools. Employing a strategy of ridicule, suspicion and relentless criticism, in a variety of ways one denies the right of others to exist or to have an opinion. Their share of the truth and their values are rejected and, as a result, the life of society is impoverished and subjected to the hubris of the powerful. Political life no longer has to do with healthy debates about long-term plans to improve people’s lives and to advance the common good, but only with slick marketing techniques primarily aimed at discrediting others. In this craven exchange of charges and counter-charges, debate degenerates into a permanent state of disagreement and confrontation.
