Gotta just knock down the lies via pointing out how ridiculous they are, then the truth just sort of comes out on his own.
You should keep in mind that a lot of the worst haters live in hater echo chambers, and as months and months and months go by, they lose sight of how absurd they sound because everyone else is saying the same thing. It's really easy to make these people look stupid, and when you make them look stupid, their stupid message begins to look stupid, too.

Arguing against this **** just gives it credibility.
There's a reason no major news network has 9/11 truthers on to "debate" the issue.
