This is just my guess, but maybe it's because the dictators use their words to climb up and become one?
For example, Adolf Hitler was in the congress for a long time before he became a dictator. He talked and gave lots of speeches that the Germans (At the time) thought were good, so they slowly trusted him and unfortunately let him become dictator.
I wouldn't use this as an answer to a quiz or test, though.
