Mel Gibson needs to stop drinking alcohol. Seriously. He needs to go cold turkey or keep his vile mouth shut by permanently lodging his foot in his mouth so he can't talk anymore unless it's reading directly from a script.
Based on his past verbal binges, his career should have been in the tank a long time ago. The talk that this latest outburst could ruin his career is just that -- talk. It will take more than racist rants for that to happen.
