Vice president Biden mocks sign language!!

Um, no, he didn't do it to mock or make fun of sign language but did it as part of his joke about how his sign language interpreter may soon suffer from tendonitis with his excessive babbling. Even the interpreter laughed at his joke. He imitated a signing movement to go with his joke. Mocked sign language itself? Not really.
This is what Biden said:

"I have more to say, but I am saying too much already because these guys get me going... and you're gonna have trouble translating all this! The poor lady, she's gonna have tendonitis by the time she finishes this."

NAD, NAACP or any other organizations won't even bother with this one so don't expect any chastising from them towards Biden.  Some people simply need to calm down over this one. Nothing worth getting your panties in a bunch or have your blood pressure burst an vein in your forehead with more of. this faux outrage. 

ADDENDUM: One more time, folks, people need to stop with the faux outrage about Biden's signing. The sign language interpreter was obviously enjoying Biden's humor and no embarrassment at all on her part. Really, the whole thing is a non-issue except for the most limp-wristed, sensitive folks out there.
