(Commentary) -- The low level of political discourse is a favorite topic for pundits who want to trash our political class. That is especially true on the left, which has often taken the position that conservatives and Tea Partiers are most to blame for coarsening political discussions and demonizing President Obama and liberals. But as anyone who regularly monitors the cable news channels knows, it’s easy to see that this assumption is largely a fiction. MSNBC, which has become the avowed home of leftism on television, has become notorious for having hosts like Chris Matthews and Al Sharpton who regularly plumb the depths with the sort of invective that would embarrass even most gutter politicians. But last Friday, Martin Bashir topped them with a scripted rant that was extreme even for him.
Reacting to a comment by Sarah Palin about the mounting national debt sentencing future American generations to the moral equivalent of “slavery,” Bashir went off the deep end. An argument can be made that slavery is, like the Holocaust, something that should not be treated as a political metaphor but rather a unique crime to which nothing—other than actual enslavement—should be compared. But Bashir wasn’t satisfied with merely reproving Palin or calling her a “dunce,” which he has done before. Instead, he dug up a historical text about the way slaves were treated in the 18th century and said Palin should be subjected to the same atrocity: to be defecated upon and to have someone urinate into her mouth.
