But you'd have to have followers who faithfully defended your actions as the right ones, even after most sensible people had seen the light and realized they were wrong.
Mussolini didn't seem to fit - does he even have defenders anymore?
Lenin? Stalin? Lenin didn't seem bloodthirsty enough, and Stalin, again, didn't seem to have very many defenders anymore.
I suppose I could have just picked someone who didn't have a propensity for violence but was just plain wrong about something important but nonlethal, who still had people jumping to his defense every time someone pointed out how wrong his view was. Or I could have gone to the other extreme and pointed out how religion has probably killed more people over the years than any other cause, and yet people still follow blindly along, but I didn't want to set off a firestorm.
Besides, I like to see Sirs get his panties in a wad. Just mention Hitler in any thread where Bush is mentioned and he gets all defensive. You don't even have to compare the two directly, just compare the blind devotion of their followers to their cause.
