I've never been banned from a board before. I try to be respective of a board's rules and members, even when I disagree with some of their views. I've disagreed with some members here, and I don't really think they can say I'm beligerant or a troublemaker.
I went to that board because it's an interesting subject to me, and I like to debate it and read other people's views on it. I came in respectfully, and remained that way throughout the duration of my stay (all of 2 days). If they haven't erased any of my posts, take a look at the "Skeptics Forum" and see for yourself (I posted under the same username as here).
These guys are paranoia personified. While browsing the site, I noticed a lot of official story people were persecuted for their beliefs - if they voiced an opposing opinion or didn't completely agree with everything Dylan Avery (the creator of Loose Change) said, they were chastised. Personal pictures of these posters were displayed, as well as their IP addresses (Avery himself posted the IP address of a poster who questioned him as a first response to his post).
If I entered that site and was starting to believe the conspiracy theory behind 9/11, I'd leave it thinking otherwise. I'd think the people running the site had embraced exactly what they profess to hate - power mongering and corruption. There's even a Free Speech Zone (named "Skeptics Forum") in which those with opposing viewpoints are allowed to post. I stayed in that forum for the most part and still got banned, presumably because of my beliefs.
I guess all that to say that the makers of Loose Change obviously only care about you if you believe them. If not, you're treated as trash. If you question the movie at all, be expected to not last long. This is the exact same mentality behind Free Speech Zones. Supporters are welcome - they can post anywhere and be seen by the masses. Dissenters are relugated to a small area and are banished if they start to get too vocal.
CTers - these are the people you wish to be aligned with?
