“Some of my best friends are…” has been a popular meme for over 100 years. While the speaker is not that type of person, he or she has friends of that type. Therefore, any criticism that the speaker makes is—according to the speaker—simply fact-based and not discriminatory.
 
“Some of my best friends are among Democrats” was said in 1880 and “Some of my best friends are Democrats” was said in 1904. “Some of my best friends are Republicans” was said in 1908.
 
“Some of my best friends are Jews” was said in 1909. “Some of My Best Friends Are—’ The experience of a Jew among Gentiles” by Montague Glass, published in The American Magazine in January 1918, made the saying famous (or infamous). The book Some of My Best Friends Are Jews by Robert Gessner was published in 1936.
 
“Some of my best friends are Catholic” and “some of my best friends are black” and “some of my best friends are gay” are other popular forms of the saying. Some of My Best Friends Are… (1971) was a film about a group of gay men and lesbians in Manhattan’s Greenwich Village.
   
   
22 October 1880, The Daily Republican (Decatur, IL), pg. 2, col. 4:
“I (Ulysses S. Grant—ed.) would not say anything, if I could help it, that should be offensive to any Democrat who might be present. I like Democrats. Some of my best friends are among Democrats, but I think for a time they should be satisfied with letting the Republican party rule this Government, at least until they can give better assurances than any they have given that they would run it in the same way for the interests of all classes and all sections.”

“Some of my best friends are Democrats and if they differ from me it is all right. I am against their doctrines, not the men.”

“I do not mean to say that all Republicans are plunderers, because some of my best friends are Republicans, but I do know that there is a tendency on the part of many to be misled by colored phrases.”

“Some of My Best Friends Are at Harvard”
Published On Wednesday, April 27, 1921 12:00 AM
The sincere and magnanimous sentiments voiced by Heywood Broun re Harvard appreciation of the Eli, should receive the hearty commendation of every advocate of “Big Three” amity. And it is to further this move for mutual friendship and understanding between these intellectual centers that I perpetrate this eulogy. Some of my best friends are at Harvard, and on that account I want to correct certain false impressions about these collegians.
(...)
I repeat it: some of my best friends are at Harvard. They are Princetonian studying in the graduate schools. And one of the chief reasons why they are my friends is because they join me in a daily even-song: “To Hell With Harvard!”—Campus Critic, In The Daily Princetonian.

Some of My Best Friends Are Yale Men
By Heywood Broun
 
12 November 1921, The Independent and the Weekly Review (New York, NY), book review by Edmund Lester Pearson, pg. 166:
Mr. Heywood Broun’s sense of humor is all but perfect. (...) But, with this entirely human exception, his writings as represented, say, by his “Seeing Things at Night” (Harcourt, Brace) strike me as invariably amusing, good-humored, and readable. He must be loved if only for his paper called “Some of My Best Friends Are Yale Men.” It required not only originality but daring for a New York newspaper man to begin to break down the aged tradition that while Harvard is given to effeminacy and spat, Yale is the nursery of sturdy American democracy. Mr. Broun pointed out to New York newspapers that an athletic victory by Harvard cannot always be set aside by the Supreme Court on the ground that Yale was not looking when it happened.

Some of my best friends are Black : the strange story of integration in America
Author: Tanner Colby
Publisher: New York : Viking, 2012.
Edition/Format:   Print book : Biography : English
Database: WorldCat
Summary:
This work chronicles America’s troubling relationship with race through four interrelated stories: the transformation of a once-racist Birmingham school system; a Kansas City neighborhood’s fight against housing discrimination; the curious racial divide of the Madison Avenue ad world; and a Louisiana Catholic parish’s forty-year effort to build an integrated church. An exploration of race relations, this book offers a portrait of race in America. In a book that is part reportage, part history, part social commentary, the author explores why the civil rights movement ultimately produced such little true integration in schools, neighborhoods, offices, and churches, the very places where social change needed to unfold. Weaving together the personal, intimate stories of everyday people, black and white, he reveals the strange, sordid history of what was supposed to be the end of Jim Crow, but turned out to be more of the same with no name. He shows us how far we have come in our journey to leave mistrust and anger behind, and how far all of us have left to go.
