I think Hitler is pretty much in a league of his own. And what peoples reactions are going to be is exactly the point. What live do you think that kid will have ? It's sad enough he has morons for parents..
He could have a normal and good life if people would just let him.
Of course we know they won't, but that says far more about other people than it ever will about this kid.
As people have already mentioned there's Joseph Stalin, or Mao Tse-Tung, or Pol Pot. I'm sure we could add more to the list but as I say, depends exactly where you're drawing the line. I'm sure there are some that would consider naming a mere mortal Jesus as sacrilegious.
