If I make a claim and they say I'm wrong,, it just as much their responsibility to prove me wrong. You can't just say wrong and expect everybody to jump through hoops. If you disagree with me show me why.
If you make a claim, as you did here, it is your responsibility to prove your claim. They need not prove you wrong. If you can't prove yourself correct then that fact you attempted to claim is assumed to be unsubstantiated, if not down right incorrect.
Let me give an example using the discussion of the scientists that began the "Global Warming" debate. They made a claim about man's effect on the global climate and warned that this will lead to evermore increasing problems with the weather. When people disagreed with them, the scientists had to prove their position. The scientist could not simply say, "No, we made the claim, now you prove us wrong." Those scientists had to produce their evidence. If others disagree with their findings it was then up to the others to prove the inaccuracy of their work, but first the evidence (the scientific findings) had to be presented. In other words, it is up to you to support your claim. If others find your evidence to be incorrect or untruthful they have to right of rebuttal.
