I've repeatedly said I know nothing about the others, only Gary Trudeau. As for your other reputable news sources, I regret to say I have heard of none of them. I have heard of CNN however, and searching their site came up with no news regarding Mr. Trudeau. Also, as I said, searching the archives of Doonesbury, the last reference to Dr. Rice was several months ago. It's from the April 7 2004 copy of Doonesbury. Is Trudeau a racist? No. Does he occasionally use words which may shock peope of sensitive personality? Yes. With a non-scientific poll I conducted where I showed this strip to students and asked if they were offended by Mr. Trudeau's depiction of Rice, 62% said no. Of the 38% that said yes, 96% of them were Republicans. Of the students in my class, 21% of the students are of African American descent, of those 0% were offended. Further, Trudeau's comment was made to illustrate Bush's tendency, which had been revealed shortly before the strip was released, to give some staff members nicknames they were not overly fond of.
Just out of curiousity, are you more upset that Trudeau "insulted" a republican, or that he insulted an African American.
Cheers
