“Political correctness” is just another way of saying that the views of people who disagree with you are frivolous, stupid, and don’t deserve to be considered or discussed.
I, personally, think that the name of the Washington Redskins is racist and hurtful to Native Americans, and should be changed. So if someone asks me what I think of the debate about the team, that’s what I say. By contrast, Virginia legislator Del Jackson Miller likes the name and wants the team to keep it. But rather than making an argument on the merits of the name, he referred to the entire debate as “political correctness on overdrive.” In other words, he’s saying, this is a false debate — just another example of “political correctness” — so I don’t have to even acknowledge concerns about racism. (Miller, in fact, claimed that it was literally fake, an issue trumped up by a “rich member of the Oneida tribe.”)
