I agree with you in theory, but in practice I just don't want to spend my time on social media arguing with someone so fundamentally ideologically opposed to me.
Sure, I could block the users individually, but I prefer to just use an instance that de-federates from cesspools of such users.
I know what you mean. I picked someone from the public timeline a few days ago and started to try and make sense of their argument.
Within just a few back and forths I realized that this person was either just bored and trolling, or I was unable to understand their perspective and it was relentless.
I still didn't block them, or their instance. I saw their message in the public timeline, it didn't arrive directly to me in any way.
