You post propaganda, dehumanize, devalue and gaslight people, behave in a rude and arrogant way. But when you get the same behaviour in return all of a sudden it's "oh boohoo, why you so meeean".
Supporter is a synonym for follower. Look it up.
I'm still waiting for those examples, where a single man (without any supporters or followers) came into power and forced the government to drastically change it's politics. Or at least tried.
I've got some examples of people who tried, but most of them are dead.
