That would just prevent people from actually being honest. The world is already way too PC and all that. People are so damn sensitive now that some honest truth and uncensored opinions would do them some good.
Sensorship is just wrong on to many levels to express them all. Everyone is entitled to their own opinions , while at the same time it does not grant them the right to force their ideals on other people. I do agree there can be a fine line between disagreeing , debating and bullying. It's up to admins to decide where that line is and to deal with those whom cross that line. Any one whether it be on line or on the street can claim to have been bullied by someone , but are they right in that claim or just unhappy that the other doesn't agree? In life the closest to an admin is a judge within a court system ; while on a web page it the page owner and the people that from the shadows police the page. They are the bottom line on what is appropriate and out of line. When a debate / poll/ discussion turn to more than that a discussion that is intended to enlighten the mind then it has gone to far , someone gets upset and things go south. Antagonism is usually a big part of what causes this situation to occur. And it's usually because of a closed mind and an open mouth. So play nice someone's big bro or sis is watching you..
Sure it's a little mean... but it's still a way for people to express their opinion. If GaG did that then a lot of people wouldn't like and possibly leave the site because it leads to excessive censoring.
