I don't understand his apology either. When I write on my blog and in comments on other blogs, I will usually walk away from my writing and re-read it later so that I am sure it says what I want and not some stupid inadvertent thing. It only makes sense to do so! I don't want to offend anybody that I don't want to offend. Keillor is a professional writer so he has some procedure in place to do the same thing. This process, of course, helps me identify thoughts I may not have thought that I held. Keillor honestly needs to re-examine his prejudices.
I have admired Keillor for years and I never thought him capable of saying things like this. It is as if his true colors are coming out. I am wondering now if I will be able to listen to my favorite Saturday night entertainment again. Has he ruined his radio show and music for me now? Probably.
