Great advice for those dealing with racists etc

I often read this column done by Cary Tennis in Salon.
He's an amazing guru (if I can call him that) with great perspective on life and it's events.
Here's a sample of a retort you can use against those idiots who have little tolerance for anything or anyone different from them. This is advice for someone has a bigoted colleague.

I suggest you call him out into the hall and in front of your colleagues say something like the following:
"Sir, I hereby notify you, in this semi-public space, before these semi-trusted colleagues, that I disagree with you on every matter under the sun."

Every time you speak your opinion on politics, religion, sex, gender, race, economics, ethnicity, intellectual style, ethics, power, television, presidents, healthcare policy, the death penalty, marriage rights, affirmative action, foreign policy, saturated fats, bottled water, bicycle lanes, commuting, public transit, mileage standards, financial regulation, zoning, coal-burning power plants, global warming, standards of office dress, suitable locations for weddings, acceptable styles of facial hair, how to properly address policemen, judges and elders, standards for advancement within this office, the political implications of the purchase of various gemstones, free-trade coffee, organic gardening, the existence and moral relevance of the Esalen Institute, the relative importance of a degree from Princeton, Sonia Sotomayor, the Rev. Jeremiah Wright, Glenn Beck, Glenn Greenwald, Christopher Hitchens, the existence of God, postmodernism, Walter Benjamin, Renoir, Rodin, the atomic bomb, Palestine, Iran, Iraq, North Korea, Taiwan, Hong Kong, the New Testament, Brazilian bikini waxes, 'American Idol,' 'Project Runway,' Tony Blair, Barack Obama and all other topics known to man herein incorporated retroactively and for all eternity, I find myself in such vehement disagreement with you such that I can scarcely believe we inhabit the same cosmos, much less the same planet, nation, state, county, municipality and office building.

Far be it from me to fathom what diabolical hand of fate placed my desk only mere feet from yours, separated by only the flimsiest of modern steel-stud and Sheetrock office partitions.

"You, sir, in short, are the Israel to my Palestine, the Yankees to my Red Sox, the Dodgers to my Giants, the apple to my orange."

Were I less wise, I would deny your very right to exist."

Being wise, however, I know that in our differences we are like rival lovers or squabbling siblings; no matter what lover, or mother, or share of arid land we squabble over, there is in our hearts enough space for whatever trees we need to grow, whatever fruits we need to harvest, whatever springs we need to drink from."

So I am not frightened or disheartened by my implacable dislike of everything you say, do and think.

On the contrary, I am reminded that by certain equally implacable laws of the universe, I must love you with every fiber of my being.

However much it pains me to the core, I must admit that I could not exist without you.

"This, sir, is the sad yet compelling fact of our mutual existence: Your office being next to mine is a torture but it is the torture of existence itself. It is also a fact that you, sir, could neither exist without me.
"Consider that for a moment, however unsettling it may be.
"I cannot claim to know why this is, nor what can be done about it. I just wish you to know that every time you raise your voice in support of one of your so-called opinions, the opposite opinion arises in my mind with equal and comparable vigor.
You are the red flag to my raging bull, the friend to my enemy and the enemy of my friend, the impediment to my dreams, the opposite of everything I adore and the embodiment of everything I could do without.

"Whenever you speak, I grit my teeth and sigh."Lesser minds and weaker spirits might clamor for a new office down the hall. But that would only create the illusion that we do not share the same universe.
The truth is, sir, that whether you were in Hong Kong and I in Saskatchewan or you in Miami and I in Beirut or I in Karachi and you in Kenosha, we would still disagree about everything under the sun; we would still orbit, as implacable opposites, the eternal unity at the center of all things, that silent, infinitely dense nucleus of existence that encompasses you, me, the Dred Scott Decision, Heidi Klum, the Harlem Globetrotters and the latest and most abstruse ruminations on string theory.

"That is the sum of all I have to say to you: I disagree with everything you say, do and think, yet I admit that without you, I myself would not exist."Therefore, I simply say, Good day, sir. Good day!"

Then, shoulders back, head high, you enter your office and slam the door loudly, well, fully, with vigor but not malice.
