Outrageous.

Fox News has gone too far (again, but this is disgusting beyond all measure). Referring to Michelle Obama as "OBAMA'S BABY MAMA"? How dare they use such a slur! There is no excuse for such blatantly sexist and racist remarks. No apology could possibly suffice. This is outrageous behavior for a "news organization", but it is even outrageous behavior for a reactionary propaganda cadre such as Fox News.

The definition of baby mama from urbandictionary.com:

baby mama

The mother of your child(ren), whom you did not marry and with whom you are not currently involved.
Oh her? She ain't nothing to me now, girl, she just my baby mama. So, can I get your number?;

And from Wikipedia:

A baby mama (also baby-mama and baby-mother) is a mother who is not married to her child's father. The Oxford English Dictionary defines baby mama as "the mother of a man's child, who is not his wife or (in most cases) his current or exclusive partner".[1]

Fox News doesn't do "news". It does targeted, political attacks clothed in entertainment. I hope Americans have the good sense to switch channels once and for all, and that Fox goes bankrupt for such callous and demeaning remarks. The posers on Fox are always first to take offense at anything, real or imagined; if they can't find enough offensive about someone in their sights, they make something up, such as questioning the patriotism of that person for not wearing a flag pin on their lapel.

They have no right to call foul in such a clear and unambiguous case of vicious, hateful propaganda.

It must stop, now.
