Hypocrisy at CBS

So, CBS fires Imus, because of the comment Imus made on-air, and CBS's statement contains this line:

"there has been much discussion of the effect language like this has on our young people, particularly young women of color trying to make their way in this society."

Well, if they were that concerned... why do they own MTV and run the trash they do? What about BET? Yup, CBS owns that too...
