"They did it too" is not a very compelling argument. It's wrong when Bill Maher says it; it's wrong when Coulter says it.
I don’t think Ann’s “justifying” her stridency by pointing out those on the left that say as much or worse.
What she’s doing is showing the comparative outrage of the “objective news broadcasters” between her statements and leftists’ statements.
She exposes the double standard, though it’s already obvious to most. She’s further grinding the left’s nose in their own bias.
