I’ve always said they live in a glass half full looking for someone to blame but your description may be just as good.
One of the worst examples floating around in their deranged internet world is a side-by-side graphic of Kyle and of Trayvon Martin, as if these two situations are at all comparable. Naturally, the graphic shows Trayvon as a child, not as the monstrous teen he developed into. It’s an inane comparison.
That’s what democrats do, too. Bring up irrelevant material; make irrelevant comparisons.
