It's not about belief or control. If you're harming the social organism by spreading verifiable falsehoods (vaccines cause autism) then you should be rooted out and treated like the cancer you're choosing to be. I can't yell fire in a theater. I'm somehow alive despite that censorship. People need to grow up.
Do we really have to go over the history of ideas that were once considered falsehoods but are now accepted as truth?
Your argument rests on the presumption that we have some kind of Oracle that can divine true information from false.

It's cool that you think humans have changed in nature significantly from the time of the Inquisitions, but when you speak like this about people it's pretty clear we haven't.
