It is the application of the DIVIDE AND RULE strategy.
The manipulators don’t want people with allied interests to get together, compare notes, and unite against the real cause of their problems.
Often disaffected groups have the clearest idea about what is amiss. They also, each, have their pet prejudices. When it looks as if the different disaffected groups are likely to get together, or individuals among them look as if they are about to create cross-linkages, the manipulators step in with “a word in your ear”.
The following are a short list, by no means complete, of standard buttons/prejudices, the manipulators will press to make an individual of a particular disaffected group close-down, when meeting another with allied concerns.
PRIMARY GROUP. OUTSIDER
Socialist/communist The stranger reads the Daily Mail, supports Israel, is against Gay Marriage and migration. Supports UKIP.
Christian The stranger supports Gay Marriage and abortion. Is homosexual.
Ethnic group The stranger is racist, wants immigration controls, By implication persecuting ethnic communities,is a fascist.
Feminist Is anti-abortion. Against public breast-feeding.
Conservative Supports handing out unlimited welfare willy-nilly. Belongs to a faux-prejudiced against group, demanding special privileges (single mother, disabled, ethnic, gay)
Anarchist Curiously, anarchists seem to be the group least dumb-founded by buttons. They appear to have taken the right-coloured tablet. If anarchists have buttons, let me know. I have yet to discover any.
This is not a complete list, but the tactic is clear. The technique involves exploiting and exaggerating stereotypes. The “word in your ear” so you will not form cross-party groupings may be a lie, or a part-truth, or out of context or exaggerated. When you look at the list it also seems that those in charge have deliberately created triggers to cause and amplify political fault lines. Such as the media-generated giants of Gay Marriage, public breast-feeding or Islamophobia. These are ploys to control the discussion and keep people diverted from the main causes of concern.
