“As a young man, I was more a white liberal than I ever tried to put on black. For all that, I ended up a “minority,” the beneficiary of affirmative action programs to redress black exclusion. And, harder to say, my brown advantage became a kind of embarrassment. For I never had an adversarial relationship to American culture. I was never at war with the tongue. Brown was no longer invisible by the time I got to college. In the white appraisal, brown skin became a coat of disadvantage, which was my advantage. Acknowledgment came at a price, then as now. (Three decades later, the price of being a published brown author is that one cannot be shelved near those one has loved. The price is segregation.) I remain at best ambivalent about those Hispanic anthologies where I end up; about those anthologies where I end up the Hispanic; about shelves at the bookstore where I look for myself and find myself. The fact that my books are published at all is the result of the slaphappy strategy of the northern black Civil Rights movement.”

Circulated in "A Coil of Rage" http://www.snopes.com/politics/obama/coilofrage.asp, a 2011 mass e-mail attributing several fabricated quotations to Obama.
Obama actually wrote, in Dreams from My Father, p. 220:
Yes, I'd seen weakness in other men — Gramps and his disappointments, Lolo [my adoptive father] and his compromise. But these men had become object lessons for me, men I might love but never emulate, <span style="color:gray">white men and brown men whose fates didn't speak to my own. It was into my father's image, the black man, son of Africa, that I'd packed all the attributes I sought in myself, the attributes of Martin and Malcolm, DuBois and Mandela.</span>

Context: I believe in recognizing every human being as a human being, neither white, black, brown nor red. When you are dealing with humanity as one family, there's no question of integration or intermarriage. It's just one human being marrying another human being, or one human being living around and with another human being.

Context: I think Ushant describes it pretty well, with that epigraph from Tom Brown’s School Days: “I’m the poet of White Horse Vale, sir, with Liberal notions under my cap!” For some reason those lines stuck in my head, and I’ve never forgotten them. This image became something I had to be. … I compelled myself all through to write an exercise in verse, in a different form, every day of the year. I turned out my page every day, of some sort — I mean I didn’t give a damn about the meaning, I just wanted to master the form — all the way from free verse, Walt Whitman, to the most elaborate of villanelles and ballad forms. Very good training. I’ve always told everybody who has ever come to me that I thought that was the first thing to do. And to study all the vowel effects and all the consonant effects and the variation in vowel sounds.
