You wouldn't happen to be related to SithMasterSean, would you?
Also, the end result of eradicating all those with totalitarian eradication agendas is eradicating yourself.
I've read a comic book where the "mastermind" of the story did exactly that. This was in an alternative universe where World War II lasted longer than in our world. The mastermind became chief of the third Reich (Hitler was dead at that point, I don't remember how), devised a plan to take out all the industrial world with a biological weapon. He also chose a select few to be sheltered in bunkers while the world healed itself, as seeds to a better world.
The thing is, he despised the Nazis. Yet not only he took their methods, he amplified them: he...
Edit :Excellent suggestions in the comments. Two of them stood out for me:
We often use "insane" to describe people whose behaviour or beliefs are below the sanity waterline. But as most must would agree here, you cannot call someone insane with a straight face just because he happens to believe in magic.
I'm currently watching Future by Design, a documentary featuring Jacque Fresco and the Venus Project. Jacque came up with this word, "unsane", to describe people who basically, aren't rational because they haven't been exposed to the right ideas yet. Which would be different from "insane", which is more about irrevocably irrational people.
I like this word, because there isn't the tone of accusation we find in "insane". This neutrality makes it easier to say that we can do something about it. Insanity should be eradicated like vermin. Unsanty on the other hand can be fixed.
So, do you think this word, "Unsanity" might be worth using?
