I don't do those, usually. Partly because I'm not smart enough to come out on top, but mostly because I find my time better spent fighting other battles. It's sad, in a way, because a good blog war is a thing of beauty and loads of fun, too. But the outcomes tend not to be good for political movements or for the people who get trampled in these arguments.
Well, ok. I don't do blog wars because I'm a cowardly goddess.
