Horowitz vs. Franken

Apparently, David Horowitz took exception to Al Franken calling him a racist. Here is the money part of the response (hat tip to Powerline):

As it happens I marched in my first civil rights protest in 1948 before Al Franken was born. For more than fifty years I have supported minorities and defended their civil rights in public word and deed, and raised millions of dollars to help inner city minorities whom racism has scarred. In fact there is no single cause -- except America's wars against totalitarian foes -- to which I have devoted myself more consistently that than that of racial equality. Not a shred of evidence exists to the contrary. I have written more than a million words on racial and political matters -- all of them public record. There is not a single sentence, or phrase, or comment of mine that could be cited to justify Franken's attack.

... My answer to Al Franken is this: I am going to post your photograph on FrontPageMag.com, which is viewed by a million visitors monthly. The photo will be identified with these words: "Al Franken,: Racist." The photo will be prominently posted until you apologize to me publicly for this attack. When you have made an apology, I will disclose my evidence for characterizing you as a racist or withdraw the charge.

And there's the picture. I rather doubt Franken will be apologizing any time soon.
