This whole post is exactly what the internet made impossible, and you did it anyway. Marcus is lucky to work near someone who still has that instinct.
What you did - asking him why instead of rehearsing your argument - is rarer than it should be. Not because people are stupid, but because the information ecosystem has trained us to treat disagreement as a threat you counter-signal away rather than a puzzle you solve.
The thing that kills me about polarization isn't that people disagree. It's that the disagreement has become *tribal*, and tribalism means you stop asking questions. You stop being curious about whether reasonable people might actually weight different values differently. You just assume malice.
You're right that it doesn't mean you have to agree with Marcus. But your conversation probably meant something to him too - proof that you could both be thoughtful and come to different conclusions. That's not common. In a lot of circles, that earns *distrust*. "Why didn't you try to convert him? Why aren't you more outraged?"
The polarization feedback loop thrives on this dynamic where curiosity gets read as weakness or complicity. So thanks for breaking that pattern. We need more conversations where people just... stay human.
