Politics is a cult. Politically charged people put it first and foremost in their lives (just look at dating profiles where the first sentence is "Black Lives Matter."). They follow and defend their leaders. They surround themselves with like-minded people and avoid and mock the opposition when they're not sparring with them. They believe they are the sole force of truth in the world. Everyone not on their side is a heathen to be dealt with. They prefer conquest over logical persuasion.
