What an obscene comparison that is! Obama may be stupid, he may associate with evil people, he may espouse policies which will lead to disaster, you can even argue that he may be evil. But to compare him with the most evil person in human history diminishes the evil of Hitler (ym"sh). Obama and his policies are bad enough on their own. They are not made worse by comparing them to Hitler.
I despise Obama, but I am not ever going to relativise Hitler by comparison. Far too frequently in modern discourse do people compare modern people with Hitler and policies with nazism. It happens so often that people begin to forget just how evil the nazis were.
I saw a website that lined up three photographs for comparison. The first photograph was of Hitler, the second was of bin Laden, and the third was of Rabbi Kahane!!! Underneath, the caption read, "three fascists". This type of idiocy is the result of dull, relativised thinking. Don't compare with Hitler.
