Ideological cleansing, I would note, exists not only under totalitarian regimes—it is present also, in a different form, in liberal Western democracies. Under the influence of politically correct extremism, individual thought and expression are too often curbed and too often replaced by empty political slogans. It is not hard to find examples today of people saying and doing things they don’t believe in, simply to fall in line with the prevailing narrative and make a superficial public statement.
