We need more healthy disagreements in general. Otherwise people have skewed worldviews and resentment, because people's beliefs don't disappear when they're not spoken (and challenged, and tested), they get stronger.<p>I'm well aware I contribute to this problem: I try not to cause conflict, especially today. But at least I respect and tolerate others even when I strongly disagree with them. And I do push back, but try to do so diplomatically.
