No one is trying to shut down scientists that don't agree; they're trying to shut down the ignorant public who's non agreement is baseless because they're getting in the way of setting public policy based on the best information science has to offer us at the moment.
That is a problem that will never go away. You will always have someone spreading incorrect information and "getting in the way" (vaccines cause autism, etc).
If the global warming data is as rock-solid as they, I wouldn't worry to much about it.
