That sucking sound you hear is Dr. Laura's career being flushed down the toilet. She might stay on the radio, but she won't really have any credibility with anyone but the racist masses.
On August 10th, Dr. Laura responded to an African-American caller who was offended that her white husband allowed racist conversation to pass without calling it out by telling said caller that her examples of racist conversation were not racist, that she was too sensitive, and then proceeded to use the "n-word" over and over again in a string.
Not content to stop there, she berated the listener until said listener hung up on her, then went off for another three minutes or so about how sensitive people are about race, and how "black speak" allows for use of the n-word with no problem.
Someone forgot her happy pills, I think. (Thanks to Media Matters for capturing the full audio.)
