I think it's more that his arguments didn't seem to have considered the situation he was addressing at all. Extraordinary claims require extraordinary proof, but he provided no evidence or reasoning at all. His comments were not particularly more substantial than "I like pizza," though their implications were a lot more harmful. I understand that you don't like to see unpopular opinions downvoted, but at the same time, vapid comments should not be protected just because they express an unpopular opinion.
