Having a discussion to form an opinion in the community is a very democratic and adult thing. This helps everyone to make up their own mind and share their opinion. In the end I believe it is very important to defederate instances that cater to conspiracy theories and spread misinformation. The reach of such content in the fediverse must be limited and it is a statement by the community that forms culture.
Thrn you don't think it's important to have a discussion. You can't think that and also be pro censoring discussionns and ideas. You can't have it both ways
I would totally agree with you if the general populace weren't as easily influenced by misinformation and indoctrination as, in fact, 5th graders.
Like, there's really nothing for anyone to make up their minds about. Don't give these people a home here; they don't need to reach the rest of us.
