Enough already. Let's start from what Ralph Nader actually said, since it's been malignantly misrepresented in nearly all of the ravings over it:
"There's no shift of power from the few to the many, which is so badly needed in this corporate government of ours in Washington, D.C., in the scenario of Barack Obama. I mean, to put it very simply, he is our first African-American president, or he will be. And we wish him well. But his choice, basically, is whether he’s going to be Uncle Sam for the people of this country, or Uncle Tom for the giant corporations who are running America into the ground."
First: this is a conditional statement. Nader didn't call Obama an "Uncle Tom"; he asked if Obama was going to be an Uncle Tom, and stated clearly that it's up to Obama to make that choice.
Second: he wasn't using the term to refer to race at all, but rather to service—in this case, crucially, service to corporations. This is further obvious from the fact that he said "the people of this country," meaning everyone in the country, not any particular race. To rephrase what he was saying: will Obama serve the people of this country, or giant corporations?
Third: "Uncle Tom" is a race-specific term in its original sense, but it is not a racial epithet. One commenter displayed his ignorance of the term by comparing it to "spic" or "shylock", as though "Uncle Tom" is somehow the same as "spearchucker" or "sambo". Not only is that wrong, but the irony is that it's unlikely a genuine racist would ever use the phrase (and certainly never pejoratively), because a genuine racist wants to see blacks being servile to whites. Can you imagine a white supremacist screaming "Uncle Tom!" at a black guy? Of course not. The people who portray it as some kind of beyond-the-pale racial slur are probably the same ones who don't know what "niggardly" means.
Not only is it not a racial epithet, but in popular usage it's expanded to refer to anyone who acts against the interests of the people they should be representing. The character of Uncle Tom has become a universal symbol for people who act against their class interests, whatever the defining aspect of that class may be: race, economic status, religion, etc. The closest analog would be "Judas". And that's clearly the expanded sense in which Nader was using it here.
Fourth: since 2000, Nader has run for president with a Native American and two Latinos—in addition to spending years arguing passionately for the interests of the poor and working poor in this country, who are overwhelmingly people of color (a point he's made repeatedly during the 2008 campaign). Attempting to tar him as racist is not just absurd, it's offensively absurd.
And finally: is Obama an Uncle Tom, going by the original meaning? Meaning: has Obama betrayed the interests of blacks? The Glen Ford article I mentioned yesterday doesn't leave much room for argument on that point. Obama has consciously used his ethnic background as a launching pad for his own ambitions, taking numerous cheap shots at blacks as a group in order to soothe white fears about any potential radicalism on his part—to let whites know that they needn't feel threatened by his racial identity. "Post-racial" for Obama apparently translates into reassuring whites by scapegoating blacks.
All that said: is "Uncle Tom" better avoided in public discourse? Yes—because it's easily misconstrued or misrepresented, especially by people who have no idea what they're talking about. But that mainly reflects a hypersensitivity to any race- or gender-specific language in this country, and not anything inherently wrong with the term itself.
In the attack interview Fox newsprick Shepard Smith foisted on him, Nader started to ask "Do you know what the historic...?"—and was cut off. Smith wasn't interested in the historical context that made the phrase so appropriate, much less the actual question Nader was posing of whether Obama will serve people or corporations; he just wanted to take a cheap shot at someone he hates, and this was a convenient bludgeon to use. And if you look at all the fevered attacks and denunciations of Nader since this non-event occurred, that's really all there is to them.
UPDATE: Thanks to cemmcs for the pointer to this Counterpunch interview with Nader:
AC: What about you calling him an Uncle Tom on Fox?
Nader: On Fox I said that as the first African American president we wish him well. The question is, will he be Uncle Sam for the people or Uncle Tom for the giant corporations which are driving America into the ground. Fox cut it off after "corporations".
He is less vulnerable to criticism and harder to criticize because of his race. When I said he was talking White Man's talk, the PC people got really upset.
It doesn't matter that he sides with destruction of the Palestinians, and sides with the embargo. It doesn't matter that he turns his back on 100 million people and won't even campaign in minority areas. It doesn't matter than he wants a bigger military budget, and an imperial foreign policy supporting various adventures of the Bush administration. It doesn't matter that he's for the death penalty, which is targeted at minorities. But if you say one thing that isn't PC, you get their attention. I tell college audiences, a gender, racial or ethnic slur gets you upset, reality doesn't get you upset.
So Fox doctored the quote to remove as much context as possible. Shocking. And Nader cuts through the trivialities with his usual acuity, and puts the focus back where it belongs.
