Do Warmers believe that censorship will cover up the questionable science of AGW?

it's clearly seen that they simply didn't know what exactly might happen in the future. in the past they thought the world was heading for a global cooling because the ice core samples from Antarctica showed that the earth has been in a frequent cycle of cooling and warming in the past and that the more common state of the planet is as an ice world. however, as the facts became much clearer, and the intervention of human beings into the current climate, they saw that we were going into the opposite direction and that they had to change their opinions. criticizing them for just not knowing is wrong but censoring is also quite wrong because your not letting the person speak at all. they should just let him show his doentary and have the big wigs of the scientific community prove him otherwise.
