It's the responsibility of the information provider to offer proof of his statements. They said it, they need to back it up.
It is NOT the responsibility of the information recipient to DISPROVE the provider's statement. One could spend their entire life attempting to disprove any crackpot, goofball claims spewed by whoever made them. Why bother? No purpose is served especially if the claim does not meet reasonable expectation (good point, Duffman77).
Every opinion is challengable. If the opinion-giver cannot support their statment or claim, they should be dismissed.
