"[T]he right wing argument that 'the left does it too' [...] justifies bad behaviour and evades responsibility by asserting moral equivalence.
"In short 'my bad conduct is acceptable and moral because my enemy engages in similar conduct.'
"In shorter 'my bad conduct is justified by what I *believe* my enemy is doing.'
"Let me explain something: If your moral floor is defined by what you imagine to be the worst quality of your enemy.... you have no moral floor. You have no morals."
