RULE 12: Pick the target, freeze it, personalize it, and polarize it.
Cut off the support network and isolate the target from sympathy. Go after people and not institutions; people hurt faster than institutions. (This is cruel, but very effective. Direct, personalized criticism and ridicule works.)

You'll notice that this is exactly what Trump is doing...watch his last speech. He names names of people in charge of nbc, macy's etc. Very personal. And he ridicules them.
