One man's crusade is hardly a race's war. There's a lot that doesn't add up, though. It's simply too hard to tell just yet. But two instances in a handful of months doesn't sound random; it sounds planned.

They’re attacking students which is the odd thing. Attacking people’s children when they’re away is a fine tactic but the only thing you are guaranteed by attacking Hogwarts is that all Wizard children of an age are affected—there is no way to really focus only on the mud muggle born. It seems much more like an attack on wizard born given their chosen locale and the statistical probability of Hogwarts housing far more children from wizard families. That is why we teach Muggle studies and not Wizard studies—there is simply a much greater need given the population’s majority.

But then why is a Wizard attacking other wizard children? You see? It’s personal, surely, but that just makes it all the harder to reason out.
