Completely agreed on your last paragraph. (And on the assessment of Calluna's post.)
And, well. Honestly, I was actually kind of hazily responding (in my rush to leave work) to the sentiment I perceived in Kimuro's comment of, "If you disagree with what the man has done in some aspect of his life, thus, his art is no longer of any use." (Which is a sentiment which has mostly been avoided in this discussion, and I'm very glad of that. Certainly, you can choose to boycott an artist, but, for example, just because I no longer buy Orson Scott Card's work doesn't mean he isn't an interesting writer.)
That said, I think Ellison's work of the 60s and 70s had several daggers to the heart, and truthfully, I can't remember anything he's written since about 1985, so seriously, I should have worded what I said better.
