Yes, that is a letter written by Gandhi to dear Adolf.  I was young once and for a while believed in this idiocy of the Pacifism movement. But I was cursed with the idea of always reading a bit more and find out if there was indeed a “Happily ever after” on things and ended up realizing there was a lot of damage done by these people. Yes, even Gandhi and if you have doubts, find out what happened in India after the Brits lowered their flag.

To keep it short: Pacifists believe in peace, not necessarily in freedom and are willing to sacrifice the latter in order to get the former.

“Gandhi and Stalin.” “What?” John asked. “I used to tell Monica that when we’d get into politics. She’d always talk about how great Gandhi was. I’d tell her the only reason Gandhi survived after his first protest was that he was dealing with the Brits. If Stalin had been running India, he’d of been dead in a second, his name forgotten.”
