JazzG British children aren't literally being ripped to shreds every single day by those bombs, are they?
Political implications are the same as your real-world implications, its just that they are so often deferred onto someone else. To act with impunity is to have no real sense that your actions have consequences. "Kill your MP" is a stupid, vicious, and counterproductive thing to say, but the underlying frustration is quite clear, isn't it? Their decisions kill, and they kill viciously, counterproductively, and stupidly. But they bear none of those consequences in any real sense. Losing your seat is a shrug of the shoulders relative to carrying the bloodied corpse of your child through the rubble of what was once your home.
