Check out this question by u/ElVeggieLoco https://www.reddit.com/r/AskHistorians/comments/1mddv0/how_tall_was_napoleon_really/?utm_source=reddit-android

In order to kill an enemy one must first dehumanise him, this process happens in all conflicts and gives us lots of vile names for former enemies. The Germans were labelled Huns, bosh Gerrie's . The French were called frogs for their supposed liking of eating frogs legs.

So it would make sense to mock the opposition leader yes? Make him seem infantile , less than human, a humuncli if you like. How scary can the 'little' man be?
