There is no fix, it's human nature. Most people are rational and balanced and willing to hear the opinions of others. And until recently the only way to have an interactive conversion was in person, or one on one remotely. Only very recently has the public square moved online. And being online gives people protection to say what they really think without fear of repercussions from others. The only way to fix it is to move discussion of heated topics to being in person only. But this will never happen. But Twitter could easily fix this with technology -- all they have to do is go back to your feed being a chronological list of the tweets from people you follow. Or create two feeds -- one that is heavily moderated and has advertising, and one that is unmoderated with no ads. Of course they won't do either one, because it lowers engagement with advertising, which is how they make money. And that makes sense, they are a for profit company. They are optimizing for their customers, the advertisers.
