Michelle Obama's speech last night at the Democratic National Convention was amazing. So were fair pay champion Lilly Ledbetter's and Iraq war hero Tammy Duckworth's. All of these women spoke powerfully about the need for pay equity, the importance of health care reform, and reproductive freedom for women.

And CNN contributor Erick Erickson's reaction to all these inspiring women? He tweeted: "First night of the Vagina Monologues in Charlotte going as expected."

Seriously? He hears powerful, eloquent women talking about crucial issues and that's his reaction? Perhaps it shouldn't be that surprising, given his history of insulting women. Earlier this year, he defended Rush Limbaugh's attacks on Sandra Fluke, saying "her testimony before congress that American taxpayers should subsidize the sexual habits of Georgetown Law School students because, God forbid, they should stop having sex if they cannot afford the pills themselves."

Erick Erickson is paid by CNN to offer conservative viewpoints--but he repeatedly offers sexist and offensive commentary. Enough is enough: CNN must fire him right away.
