Well, that's an interesting theory, but it shouldn't be illegal. I mean... medical doctors get things wrong all the time, say stuff, have opinions, and publish theories about how the human body, substances, and the environment interact, and no one bans them from travel or labels them terrorists.

So, it's a kind of weird idea. So what? We used to believe that smoking was good for the lungs, and that butter caused heart attacks. Newer data indicates that smoking isn't very good for you, and that vegetable-based spreads are worse for you than butter. Oh, and apparently smoking can potentially lower some folks' risk of getting seriously sick from Covid. So, that's cool.

Our understandings of how things work shift constantly. If you ban theories, ideas, and possibilities, you're basically banning genuine science, and putting "science" in the hands of governments, corporations, and the media.
