The correct path is to teach everyone logic and scientific thought so that people can effectively determine the truth for themselves.
Instead, we seem to treat students as if they were all idiots who must be "protected" from "wrong information". You can't do that without creating obedient sheep. You may be one of those who think obedient sheep would be a good thing, until someone else, with completely wacky ideas, starts leading your sheep off into the hinterlands.
Instead of trying to suppress all the information we think is wrong, we should teach people how to think and how to evaluate information. That really is the only way to effectively protect them.
