Well, in the end nothing will happen.
We can always hope, of course, but I don't think Bill O'Reilly's racist remarks about a restaurant will get him fired (nor will Rush Limbaugh's remarks about "phoney soldiers" get him turfed)
Remember, Don Imus smeared a hard-working group of serious and dedicated young women as "knappy-headed ho's" and it was the culminating incident of a long history of racist remarks and Imus STILL almost kept his job. It wasn't until the MSNBC staff threatened to quit that the network finally realized that Imus had to go.
Fox employees aren't going to go toe-to-toe with O'Reilly -- he makes too much money for the network. If they didn't fire him because of the falafel lawsuit, they won't fire him over this.
But that said, let's everybody make the O'Reilly "scandal" last as long as we can...
