There are certainly people who think that Covid is a hoax. There aren't many, but they do exist.
If you look at the paper the article cites as evidence COVID denial exists, it's actually also not true. They ask people variants of "do you think the danger of COVID was exaggerated" and when people say yes, they get classed as people who think COVID is a hoax. So the claim that people think COVID is a hoax, is a hoax. This is what "science" has become.
Sure, but there's no point writing an article about such a non-existent position. Unless the point is to strawman. Which we have seen far too much of lately.
Ukraine doesn't exist. This is all fake news by western countries to smear Russia.
Would you like to debate me on whether or not Ukraine exists?
No, that's not a real position to debate. Instead what the article is doing is no different than all the 'science deniers' stuff. How dare you deny the dogma of science!
