@nate_river I agree with most of that.. but I'd suggest a few things..
1) if your goal is to surround yourself with what you enjoy then there is no need to block, muting accomplishes that, block only serves the purpose of where you think the person **is** a bad person and thus do not trust them to read your otherwise publicly accessible posts
2) Even muting is a rather immature first-line approach if everyone is otherwise respectful and your goal is simply to surround yourself with good people. now I say this in the context of someone you've had an exchange with, and im not referring to muting threads, that's normal. In my mind two mature respectful adults should simply be able to have one person say to the other "Can you please leave me alone" or "I do not wish to have these sorts of conversations in the future. that would be the end of it. The issue with muting is you let someone talk and talk without knowing you can't hear them and it is rude to them to let them waste that effort without politely asking first.
So in a way i agree with your assessment in part, but its really an immature way for people to go about resolving differences or to try to disconnect from someone you dont want to interact with, at least as a first-attempt.
That said, you do you, I certainly wont give anyone shit for blocking or muting anyone, that is your choice and feel free to exercise that right at your discretion of course.
