If there's a second thing you don't do, it's offer any criticism of Ghandi.
People cling so irrationally to the persona that have been drilled into their head throughout their entire life that offering any insight or raising any contradictory perspectives on certain characters draws the same response you'd get if you went up to a devout religious person and started asking about their crazy mythology. That is, you encounter a brick-wall that only spouts that you are wrong, because (instead of The Bible Says So) "she was a saint" or "he was a pacifist". And that's as far as you'll get. People who have no investment or interest in either person will be highly offended that you would dare make any assertions.
Hyped figures perpetuated by media and society are destined to be remembered this way for eternity and any contradictions -- no matter how scholarly -- will always be categorized as hateful.
Oh, if there's a third thing you don't do, it's offer any criticism of Nelson Mandela.
Oh, and if there's a fourth thing you don't do, it's offer any criticism of Che Guevara.
