I rarely see offensive content, even on the federated timeline. And I think I've never asked #qoto admins for anyone to be blocked or banned. Isn't censorship one of the major concerns (historically with the right, now with the left) on face and twit and others?
I've realized I don't see a bunch of offensive stuff here because
1. I choose to not be offended whenever possible.
2. I want to interact and not just to win some internet argument. Do people still try to win? I used get sucked in and rarely do these days.
3. I have readily blocked or muted individuals and entire servers (primarily for trolls and servers set up for... "adult Content")
My follows list spans across politics, religion, etc. I have strong convictions, beliefs, and rationale. And these aren't at risk from being exposed to yours that are different. In fact my ideas are clarified, adjusted, refined, and solidified by exposure and interaction with those who differ from me.
