@MeidasTouch Someone I used to talk to on another site used to call people like that "nīðings" or "nīthings." It roughly translates to honorless or villainous, but means something more like "this person, due to their actions, should be fair game with every hand against them."
The right, of course, would no doubt try to equate this with their own habit of declaring open season on entire demographics just for existing. But I'm sure we can all see why THAT'S a faulty analogy.
