"You should be horse-whipped for the insult you have paid to the highest office of our nation." That is the opening sentence in a searing open letter from movie critic Roger Ebert to conservative radio host Rush Limbaugh.

Why is Ebert so upset to suggest an entertainer should be beaten like an animal? As you may have heard, Limbaugh has been critical of President Barack Obama's response to the earthquake in Haiti. On Wednesday, Limbaugh blasted Obama for responding so quickly to the crises, then suggested that your hard-earned dollars could be stolen if you donate to relief agencies listed on the White House Web site.
