That was a phrase Mark Shea used to describe various radical leftwing groups, especially atheists when they would swoop in to remove a memorial cross or some Christian tribute on public ground. I always liked that because it fit. They are the type of people you wouldn't mind seeing take a seat on a commode at Jurassic Park. If this story is halfway true, it certainly applies to them.
To be gracious, knowing the proud contempt that many millennials and post-millennials have for history of any type, it could be that they've never heard of Pearl Harbor or anything to do with it. Or, on the off chance that they have, they don't link it to any particular date. I'm willing to believe that for the sake of giving the benefit of the doubt. If that's the case, then they don't deserve the label Human Toothache. For why single them out for being as ignorant as our media, culture and education institutions have wanted them to be.
