No, but I know who McWhorter is. He's a syndicated columnist or at least a columnist at the WaPo, right? 
I have no problem with language moving, changing, shifting. I have no problem with what fatguyinalittlecoat said when he said he wanted to be able to use the dictionary even if I didn't like roadkill1292. I thought that was funny. The three or four guys I always think of when it comes to language are William Safire, William F. Buckley, Jr., David Foster Wallace, and Bryan Garner.
See, this is better. We probably disagree politically, but a good book recommendation or at least common ground is better than brawling. It leaves me in a better mood, anyway.
