It's super hard to have good faith discussions on the internet for years now. When someone has different opinions, those opinions are associated with certain groups (liberals, conservatives, etc). And it's very easy to demonize other groups, because social media shows curated content with extremely idiotic and malicious people in that group. Even if we have only slightly biased opinions, the algorithm knows watching content which follow your existing opinions are super engaging. We can't resist the satisfaction and dopamine hit of finding out our opinion is right. Attacking obviously wrong people from a moral high ground without risking being attacked by other people is also really attractive. After consuming such content for a long time, we come to see other groups as nothing but evil, and it makes it very difficult to have good faith conversations.
