There's nothing wrong with being 'extreme' really. Radical justice is better than mediocre injustice. But that doesn't negate a need for accuracy. 'Propaganda', by definition, isn't supposed to be accurate. It's myth building "for a purpose". Creating a mirrage to move the masses in the direction you choose.
In practice, by making others dependant on a myth, you are enslaving yourself to their false beliefs. If carried on, this intellectual, two sided, slavery itself will lead to slow death. But also, if the myth itself ends, you risk doing so with it.
