Is political correctness killing American society?

Political correctness is a form of censorship used by liberals to advance their socialist agenda. The biggest tragedy in American society is that instead of combating racism, & all forms of prejudice in general, we define prejudice by the standards of political correctness. Liberals accuse anyone who's against affirmative action, illegal immigration, or hate crime laws of being a racist. Actual racism is prejudice on the basis of race. Political correctness has made it socially acceptable to denigrate Whites, Christians, conservatives, the US military, the patriotic, & members of any non-White group who exhibit these characteristics. Do the same thing against non-Whites, Muslims, liberals, the poor, the marginalized, & you're called a Nazi. There is nothing correct about political correctness.
