Yeah, like I have to prove anything to a libtard like you.
No, you don't HAVE to. But, you're the one who made the claim and, by the rules of debate, it's up to YOU to prove what you said.
But, that's OK. I know you can't, you know you can't, and you're not the first Nutter to be taken to task for making unfounded, unprovable, unsubstantiated allegations against President Obama so don't feel too badly.
Being unable to prove anything is pretty much SOP for the Nutter right and why I've been so successful at killing right wing threads.
