c/drugs would you also delete it? because they spread drugs propaganda, deleting a comunity helps people? people will stop using drugs because you are censoring them? nope you just created the streisand effect
Yhe purpose of rules and moderation is that everyone behaves well, eithoit personal insults etc. Not to decide what is true or false (thats what discussions are for).
If its really misinformation like you say, it should be no problem to debunk it with actual arguments. And if you dont like the community, you can personally block it.
I understand your point, but I think what we all learned very recently is that idiots will be idiots regardless of what you show them.
Look at people from /r/joerogan for example, antivax and antimasks and such. No matter what information you show them, they always have their own biased (non factual, wrong) sources. They just hide in that. Is it not better to just cut the propagation of false information from the start? Avoid the congregation of sick/wrong ideas?
You can't actually convince them that the way they think is wrong. They're programmed at this point. Refusing to give them an echo chamber is the best option.
