Why do you say that people don't change their opinions based on evidence? I've seen it happen. Hell, I've done it myself. Even the people posting in favor of these sorts of topics cite "evidence", for different values of the word "evidence". White supremacists talk about "color" on "color" crime stats, flat earthers mention the horizon not appearing curved (had to look one up), climate "deniers" point to sunspot cycles, anti-vaxxers reference that one autism study, etc, etc. Obviously people do change their opinions based on evidence. They just don't necessarily look for evidence against the topic, mainly, or don't question the evidence provided. These are things they might be exposed to if the conversations weren't banned or relegated to "bubbles". There is also the potential problem of censoring people who actually do hold a valid evidence-based opinion on a topic, it's just not one that's politically en vogue currently. Not to mention all the topics where it isn't clear what the truth is, despite a plethora of evidence for and against, and the person in charge holds a strong opinion on it. What I'm saying, I guess, is "citation needed". Show me your evidence that people don't change their opinions based on evidence and maybe I'll change my opinion on this topic :)
