They were egregious, misogynistic at times, scorched earth swipes, you name it. And no doubt they were used by his enemies as ammunition. And it's worth noting that Grenell was a pitbull like Bolton: abrasive, uncompromising, fanatical, divisive. But that, in a way, is the point. He behaved as today's young Republican Turks do. He was one of the crowd in that way as in so many others. And I'm not defending those tweets or the style or the culture that Grenell relished. All I'm saying is that those tweets would have been trivia if he had not been openly gay. And Romney's silence is more eloquent than his words could ever be.
