What Does It Mean to Be Called Racist?

This post, from a blog that I follow, sums up the topic and comments from this post, from another blog that I follow.  I think that the highlighted comments are spot on, especially comment #1.  I think that a lot of white folks have no idea what institutionalized racism is, let alone how it affects the schema through which everyone, white black or in between, views the world.  This is something that I wonder about every time a white person, celebrity or otherwise, acts as if being called a racist is the worst possible thing in the world.  I can think of a lot worse words, and most of them were created by the ancestors of the same white people who get all indignant about being told that they've said something racist.
