Really? "You lie" is a racist remark?
No, it's all about the context of Joe Wilson's career, his past attacks on Strom Thurmond's daughter, his advocacy on racially polarizing issues, and the fact that several politicians of his age and background (including Lynn Westmoreland, who called Obama "uppity," and Saxby Chambliss, who warned Obama to show "humility" before him at his upcoming address) and many, many protesters have a strange problem not insisting the President show deference and respect to them befitting their 1950s upbringing.
If you don't see it, then there's nothing to discuss. But you do have to look at the big picture.
Of course Brittain will urge that all criticism of Obama (at least from the right) is "racist."
No need to think, examine the facts. Just do a little childish name-calling (the latin term is ad hominen attack).
Sorry Brittain, but you race card has been declined.
