I grew up in Pennsylvania, about an hour from Lancaster county where many Amish live. I was also raised as a Moravian in Bethlehem, PA. They also were pacifists--much to George Washington's chagrin. They refused to fight in the revolutionary war, and they would treat anyone--American, British, French, or Native American, in their hospital. Their gravestones are also flat and the same size for everyone because they believed everyone was equal under God. When someone died, they were put into the next available grave, so a Native American might be right next to a prominent community leader.
Even though I eventually rejected Christianity, I still hold those values as very important and special.
Also, my understanding of pacifism isn't that one never fights, but only uses it as a last resort. Which verse has Jesus saying something like, "I come not to bring peace, but a sword"?
As for Hitler, what do you think about the American soldier who had him a bayonet point in a foxhole in WWI, but let him live? Just throwing it out.
