Why atheism always has a burden of proof

[Vincenzo Vinny G.]

I disbelieve that claim. Fulfill your burden of proof!

now your getting it.

In standard written English, when two negatives are used in one sentence, the negatives are understood to cancel one another and produce a weakened affirmative.

I'm skeptical of your source. Not having enough reason to believe your source, I have no reason to believe your evidence, and therefore I reject it.
