cofty, do you think freedom of speech means that a person should be able to publicly teach that tea made with Oleander leaves (deadly poison!) is a good remedy for the common cold, without facing any criminal charges?
Don't governments have a responsibility to protect their gullible, ignorant citizens? If govts have a responsibility to protect the physically weak from being harmed by others then they also have a responsibility to protect the intellectually weak from being harmed by others.
Freedom of speech is good as long as the speech does not hamper the freedom of life and wellbeing of others. Tell me what harm results from criminalising the public dissemination of ideas which are not provably true and which, when followed, result in the harm of others.
