Why does everyone I know always want to summon Hitler in a Fate RP? ;-;

Well, I suppose since this Fate RP is entirely different, it would be possible to summon Hitler. Although, anything too modern I will have to say no. I think the latest I'd allow would be anything 2000. Anything this century would probably be a no-no. Although, if people are uncomfortable with some people being summoned, then I will ably by their wishes and say that they can't be summoned.
