Militant Christianity has an extensive history, tracing from Indo-European conquests in the Bronze Age, four thousand years ago, to the AD 312 victory of the ruthless Roman emperor Constantine, and beyond. Indo-Europeans' ethos of war as the natural human condition and glorifying battle persisted through the Protestant Reformation, colonization of America, capitalist industrialization and today's 'marketing era' promoting competition. The book is written as a lively chronicle making clear the astounding power of the ancient cultural tradition embedding our language, and the real battle we face to contain this 'Christian' jihad.
