Well, Ake, there are genuine disagreements around - but I don't think that a bullshit label like "politically correct" helps, whether that's being presented as a good thing or a bad thing.

And I can hardly rememeber any occasions where anyone has actually useed that label except as something to attack. Leaving aside people whose concerns are just about lawsuits and legal issues, and I do leave such people aside.

But courtesy and consideration for other people who often get treated without either of those thinsg does matter a great deal, and I don't actually think there are many people who would disagree with that as a ruling principle, though we might disagree over details about what that should imply in practice.
