demagoguery

Demagoguery is an appeal to people that plays on their emotions and prejudices rather than on their rational side.

Demagoguery is a manipulative approach — often associated with dictators and sleazy politicians — that appeals to the worst nature of people. Demagoguery isn't based on reason, issues, and doing the right thing; it's based on stirring up fear and hatred to control people. For example, a politician who stirs up a fear of immigrants to distract from other issues is using demagoguery. Demagoguery is one of the most negative aspects of politics, but it's also one that's all too common.
