> This just feels like an excuse to find a way to filter human communication
Interesting. I've modded a fair amount of communities and the censorship argument to moderated discussion comes up frequently as new rules are implemented.
From an online discussion point of view I don't think it holds merit at all. If I run a football board and have a rule that says "no basketball talk" that's my prerogative.
As long as it's not government driven, censorship is perfectly fine (if you don't like the rules of my service, you are free to use someone else's). When it is government driven, censorship is murky territory at best, but not immediately bad and illegal/unconstitutional. The FCC in some form or another has rules against broadcasting certain types of content. You can't swear, you can't show nudity (or certain types of nudity anyways). That's government driven censorship, and its largely accepted.
Slashdot had a hands off approach for a long time. I couldn't go to their site without seeing a n-word reference in the comments because their approach was abused. If you go to reddit, facebook, twitter, snapchat, instagram, or any other major site you run into astroturfing campaigns. We've grown to accept that Microsoft is good at it and Sony is bad at it. But somehow when AT&T does it, it's evil.
I don't know what the solution looks like. I just know that we need to evolve. Filtering communication is part of it. A bigger part of it would be finding ways to drive healthier habits.
