Yes, how terrible that large numbers of people can not only believe "harmful" things but also freely share their ideas with others. It behooves society to stop both of these things from being too easy, no? What's more harmful? That basic freedom to believe whatever you please and share it with like-minded people without imposing on others against their will, or having legal authority to impose against such voluntary sharing for supposedly lofty ideals of fighting harmful thinking? (However you want to define harmful)
