Bang! Bang! Bang!
Seriously though Battuta, you're fighting windmills. Internet discussions are much easier to walk away from than real life ones. Experience so far has shown participants in said discussions as being extremely unlikely to change their opinions even in the face of overwhelming counter-arguments. A person will just walk away from a discussion for a multitude of reasons, including:
a) person A's opinions are consistently being proven wrong by person B armed with substantiated facts, which is annoying so rather than go through the uncomfortable process of adjusting it's views according to reality the person A just leaves - as I will just point out this isn't the worst thing person A can do;
b) person A's opinions are consistently being proven wrong but that person decides to just ignore all the facts and continue to post the same thing in a variety of very similar ways, sometimes in multiple threads. Person B decides it has better things to do with it's life and leaves to prevent an aneurism;
c) person A belongs to the unemployed unwashed masses group and can't afford the internet, and has to wait until the court restriction of accessing the public library expires before they can access free wi-fi again;
d) person A does not believe in rationality;
e) person A is 12;
f) Snuffleupagii related reasons,
etc.
It prevents good discourse and is annoying, but at best this thread is going to curb that a bit for a short while.
