Exactly, it's like how the current scientific consensus is that the earth is round, but many enterprising individuals are busy trying to prove their theory that the earth is flat.
Do you think they should be suppressed?
Yes. I think clearly wrong and/or fraudulent people should not be held up as equals to experts. We have in fact learned some things in the last few centuries.
I must say I find it quite dishonest and hypocritical to use examples of theories which didn't impact humans' lives at all, or, if they did, only on the level of an individual -- to use these examples as a comparison with climate change. These beliefs have nothing to do with climate change which effects have already started being visible for decades now. This has nothing to do with medicine, it's biology, geology, meteorology. Hundreds of species are disappearing, sea level rises are undeniable, temperatures are rising as well and forest fires are increasing. These are facts.
