How and why do entire communities behave irrationally? Mass Insanity explores the subjects of a totalitarian mindset, the clash of identities, and how societies indoctrinate their members. It discusses the mass migration of Muslims to the West, the identity crisis engulfing European societies, and the complicity of the elites. By employing psychological theories to analyse Islam, the decay of Western civilisation, and the arising difficulties, the author shows these issues from a basic human level.
