Hitler preached about peace, making life better, and
all the same things
Martin Luther King, John Lennon, or Gandhi preached about. The
difference between them was what in they practiced, not in what they preached.
Anybody can talk about peace and making
the world better,
no matter what their true intentions are. Hitler is an example of someone who could deliver convincing speeches about how and what he wanted to do to make
the world better, but it was his intentions he was acting on, not his words.
