Racists don't like to admit that they're racist. I like using TexasFred to illustrate this point, but this post serves that purpose too and has the added benefit of being linkable. TexasFred, you know, doesn't like for me to link to him. Makes him mad, and Lord knows we don't want to make TexasFred any madder than he already is.
I suppose my own perspectives on this issue are influenced by the experiences of my mother. She was raised as a woman of privilege in the deep south and I recall conversations with her about the struggle she experienced during the civil rights movement of the 60's and early 70's as it gradually dawned on her how racist the attitudes she had grown up with were. She was mortified, but then she is a woman of rare compassion and introspection and I've always felt lucky to have learned from her.
