I think I've finally come to realize that it's not worth it trying to argue with people on the internet.

A good debate requires that all participating parties are at least partially willing to be proven wrong if counter evidence demands it. People who are so invested and so firmly believe in something that they would post about it on the internet are highly unlikely to fulfill said requirement. There's simply too much personal attachment to the subject at stake that they can't afford losing.

Furthermore, you can not reason with idiots. Idiots are not rational. You can not convince an idiot that he is wrong, because the sheer fact that he is an idiot means that he is too illogical and irrational to even begin to understand that his arguments and line of thinking are flawed.
