Empires and rulers throughout history have used this tactic to weaken opposition by setting groups against each other, preventing a united front. If people are fighting each other, they often don’t focus on the root causes of their problems, or the structures that perpetuate them. If people are arguing about flags, statues, or what someone said on social media, they’re not talking about tax avoidance, corruption, or how wealth is concentrated at the top.
Does anyone have ideas on how unity can be built? At the moment, you're either a Marxist or a Nazi with nothing in between.
