According to Dr. Gregory Stanton, author of the 8 Stages of Genocide (later republished as the 10 Stages), Polarization is used to "drive the groups apart. Hate groups broadcast polarizing propaganda and obstruct alternative points of view. Extremist target moderates, intimidating and silencing the center. Moderates from the perpetrators’ own group are most able to stop genocide, so are the first to be arrested (and killed). The dominant group passes emergency laws or decrees that grants them total power over the targeted group. The laws erode fundamental civil rights and liberties, especially Freedom of Speech and Press, targeted groups are thus incapable of legal avenues of self-defense, and the dominant group has total control.
