So, anyone voicing opposition to that law is merely being "politically correct"? If so, that's an awfully tidy dismissal of the opinions of millions of Americans.
My understanding of the term "politically correct" is that it refers to people who aren't voicing sincere opinions, who are saying only what they feel is safe and acceptable to say.
I can't see where that applies here.
But I suspect that the term "political correctness" no longer really means that, for most who use it. Rather, it means something along the lines of "voicing a centrist, liberal, or progressive opinion or viewpoint," which allows the observer to dismiss said viewpoint as "political correctness."
