A difference between common carriers like the phone company and the post office vs. internet websites is that your communication on common carriers is usually private. There's no reason for any moderation to take place. Whereas on a web forum such as this, moderation is necessary for conversations to not descend into chaos. Frankly I don't understand why people think moderation has gone too far. Is it that e.g. Twitter shouldn't be allowed to silence unpopular opinions because silencing unpopular opinions is always bad? Or is it that it's bad because Twitter is huge and influential. Would you have a problem with someone silencing a gun control fanatic who has appeared unwelcome on their private little gun collectors' website?
