From Ryan Holiday:
As we’ve become more polarized and more algorithmically sorted, we care a lot less about the people who think differently than us and put little effort into persuading them. That’s because persuasion is no longer the goal—it’s signaling. And with signaling, it’s vehemence that matters, not quality.
Holiday goes on to talk about political correctness, anti-intellectualism1 and polarization in our media.
Here is the final point as well:
If you can’t be kind, if you won’t empathize, then you’re not on the team. That team is Team Humanity, where we are all in this thing together. Where we are all flawed and imperfect. Where we treat other people’s point of view as charitably as we treat our own. Where we are civilized and respectful and, above all, kind to each other—particularly the less fortunate, the mistaken, and the afraid.
