Same thing happened at my place over pepe emojis. What strikes me is the conversation centered around perceptions. "It makes me feel bad so take it down or else. End of the conversation" No opportunity to "work it out". Everything is confrontational, win or lose kind of thing. Each incident seems benign on its own, but kills soul in the long run. If you're ever caught in that crossfire, the reasonable stance is "just do what they say, don't make a scene, think of your career"
