There probably are servers that try to be more tolerant or other opinions, but I think social media could be improved by something like in this video. I put a timestamp but TL;DW not just upvote+downvote, yes or no, but more diverse reactions like "partially agree", "offtopic", "you have convinced me", "informative", "misses the point", etc.

So not just up and down, but left, right, diagonal and every which way to have a broader spectrum of human reactions instead of a binary one.

Additionally, add a more structured conversation flow depending on the community. A community for questions looks more like quora, a science community could maybe want options to add sources and have them aggregated in a thread, and so on.
