It's rather funny when you think about it. You hear about censorship in countries like China or in crazy closed cults or in the past when Fascism and Communism were more prevalent.
You don't have to travel to these places or back in time to see this in action however all you have to do is go onto a conspiracy board, or even just a website.
They rely on censorship and the hope that you are too lazy to bother double checking their quotes, facts, claims, random crazy stuff.
Now if you go to a forum with debunkers on it and watch the endless battle that we fight with these people you will see that there are many, many insults thrown at the debunkers. We are treated like Goldstein's agents.
The require censorship to thrive, because the less of the facts their audience knows the more likely they are to believe what is in front of them.
This is one thing that makes groups like the 9/11 CTs far more hypocritical then normal. They claim "the government controls and censors the media" while censoring their own work. I fail to see how they can claim to be "patriots" while they so willingly do what they claim the government is doing.
It makes them look like two sides of the same coin.
Except that they aren't really.
