[This sigh has its origins far older than Rogue... and so does the fact that she's even bothering to explain it.] It's always the same thing - someone thinks they're 'superior,' so they try to wipe out everyone else. It happens all the time with humans, and now it's happening between mutants and humans... and now it's happening here. You can dress it up however you want to, but there's nothing 'superior' about someone who wants to kill everyone else - it's nothing but hatred and fear. And this isn't you, Vash. And if you try to do something like that here, we'll stop you.
