The core problem here is that our technology for discourse is basically twitter and "voting with likes". The algorithms are optimized for attention and likes, so the mob wins - not the best argument.

IF we fixed THAT problem (with new technology, an early one is https://www.kialo.com/tour, but it's not good enough), we can have what you want.

Right now, we're effectively the same tech level as the 1900s (perhaps in a more dangerous way) w.r.t finding truth or the "right" arguments

I’ve never been a fan of voting with likes either. I’d be all in for legislatively banning up and down vote systems. You will get minimal traction here though as the political left use these content voting systems to focus effort and gamify division.
