Isolate and demonize that enemy by unleashing and protecting the utterance of overt and coded name-calling and verbal abuse. Employ ad hominem attacks as legitimate charges against that enemy.
Palisade all art forms; monitor, discredit or expel those that challenge or destabilise processes of demonisation and deification.
Subvert and malign all representatives of and sympathisers with this constructed enemy.
Solicit, from among the enemy, collaborators who agree with and can sanitize the dispossession process.
Pathologize the enemy in scholarly and popular mediums; recycle, for example, scientific racism and the myths of racial superiority in order to naturalize the pathology.
Criminalise the enemy. Then prepare, budget for and rationalise the building of holding arenas for the enemy — especially its males and absolutely its children.
Reward mindlessness and apathy with monumentalized entertainments and with little pleasures, tiny seductions, a few minutes on television, a few lines in the press, a little pseudo-success, the illusion of power and influence, a little fun, a little style, a little consequence.
Maintain, at all costs, silence.
