Where on the internet has anyone said Japan "deserved" the earthquake because of a long-ago war?
That is, excepting for fakers alleging to be from our side.
I doubt the people making those posts are even alleging to be from our side, Frank. That's just something the primitives made up to fit their narrative.
The internet is full of trolls and tends to bring out the worst in some people. For all the DUmbasses know those posters could just be totally apolitical attention whores looking for any excuse to stir the pot. You see it all the time at lightly- or non-moderated sites like YouTube or LiveLeak. FaceBook is no different. People say outrageous things just to create outrage, and of course DUers will grasp at any straw in order to demonize their opponents.
Dummies, on the other hand, completely own their vile proclamations. When they refer to babies as "crotch-droppings", slander innocent people, celebrate the death of individuals, it arises from their deeply-held core beliefs. They revel in them, take pride in them, and see them as virtuous, which makes them a thousand times sicker than any random shit-stirrer on FaceBook.
