It reminds me of what Norman Finkelstein wrote after Christopher Hitchens' death. His comment was specific to Hitchens, but I think pretty much the same about Rivers:
I get no satisfaction from Hitchens's passing.
Although he was the last to know it, every death is a tragedy, if only for the bereft child--or, as in the case of Cindy Sheehan, bereft parent--left behind.
But, still, life is full of surprises.
No one should be too smug in his certitudes.
And if you've made a career of pissing on other people's mostly innocuous beliefs, should it surprise that outside the tiny tent called Vanity Fair, your memory stinks of urine?
