Christopher Hitchens.

The legendary English barrister F.E. Smith (later Lord Birkenhead) was a dear friend of Winston Churchill until Smith's death in 1930. (Smith was also the master of the devastating courtroom put-down, deployed as often against judges as against the opposing party).

Smith clearly saw the oft-scattershot judgment of his impetuous friend, and remarked:

"When Winston is right, he's absolutely right. When he's wrong...well, my God."

I think that judgment applies to Mr. Hitchens as well. Here's one for the "absolutely right" file, as he destroys Chris Hedges in a religious debate. Look for Hedges' no mas moment at the end.
