You mean, it’s now technically possible to prove a negative, even though it’s logically impossible? Wow! What’ll they think up next?/s
Your comment is racist. Allow me:
In business, you can either be in the black, or the red. Being in the black is profit, being in the red is loss. You mentioned the word negative, which correlates to a negative profit, or a loss. The opposite of a loss (being in the red) is black.
Obama is black.
YOU ARE A RACIST. < /liberal>
