There was an interesting commentary in the Washington Post by Richard Cohen which followed up on the comments made last October by conservative Grover Norquist.
"...among other things, Norquist compared the estate tax to the Holocaust."
"...This is unbridled selfishness in the guise of ideology and makes wealth the moral equivalent of ethnicity or religion or even sexual preference. To Norquist, distinguishing between rich and poor is like making a selection at Auschwitz. It not only trivializes the Holocaust, it collapses all moral distinctions."
