This is exactly why I on selected platforms have bothered arguing with people spreading their lies about creationism/anti-evolution, flat earth, alternative medicine, anti-vaccination, conspicary theories idiocies, and other science denial and fact resistence. It is mainly to demonstrate to the silent reader that those ideas should not be taken at face value, for good reasons. Also, the above mentioned idiocy will not disappear after the idiot left his/her keyboard, and it’s not a good idea to let said crap shine like a lighthouse through search engines.
Another reason is that I find it mildly amusing to argue with them.
