I don't understand what you mean, anyway. You don't like his business, you don't like his writing, but you have all sorts of cares for him? Er .. why? What would he have to do to make you finally relinquish your sympathy?
In my book, a man is but the sum of his actions. I can't stand Arrington's actions, therefore I can't stand him, ergo I have no sympathy for the hatred his actions have engendered amongst sum.
And one more thing - the man who spat in his face may be contemptible, but it doesn't doesn't fit my model of how "cowards" behave either. The coward would be writing spiteful comments anonymously on blogs. Walking up to someone and spitting in their face takes balls, IMO. Not exactly my preferred means of communication but it certainly got the point across.
