“The real rise of the phrase [political correctness] can be traced to the early 1990’s, when people started to use it to critique or just lament the policing of ideas that are out of step with the hegemony of liberalism in American society, post civil rights and post women’s liberation. In doing so they also effectively signaled themselves as ‘free thinking,” said Carole Bell, a professor of communication at Northeastern University in Boston.
But in case of some conservatives backing Trump, Bell argued, “it’s an expression of the racial resentment that political scientists have long known were animating much of our political discourse around identity. But it’s masked as a concern for free speech.”
