I don't know if the the more reasonable but equivalent slogans got replaced by the more spicy ones in some sort of meme survival of the fittest, or if it's a trend of today's social movements to use divisive or easy to misunderstand slogans on purpose.

Ex: "Black lives matter too" vs "black lives matter". or "replace / reboot the police" vs "defund the police". The police one I'm having a hard time thinking of a slogan that would be better, maybe that's why it stuck.
