I’m no fan of the current war on "misinformation” — if anything, I’m a conscientious objector — and one of the reasons is the term’s pedigree.
Although the Grammar Curmudgeon in me freely admits that the word is a perfectly fine one, the effort by public and private sector alike to hunt down misinformers to keep them from misinforming the public represents a return to the bad old days that once upon a time liberalism sensibly opposed.
First, as to the word itself.
