The radical left and radical right share a trait of blurring definitions in order to get people riled up. In fact, I'd suggest (though I cannot prove) that the tendency to be imprecise in definitions is a telltale sign that the movement doing this is demagogic and, in the end, antidemocratic. Trump set about to redefine 'fake news' for example. All of the sudden mainstream media were the enemy of the people.
