I first started following Kathy Kattenburg on Twitter after she showed kindness to me following an article about my sex abuse in the Washington Post, at a time when many of my supposedly like-minded conservatives had not. It seemed like a minor example of cross-the-aisle political civility. But it soon revealed itself to be a lesson in how elusive civility can be these days, especially online, in an age when we’re often told (or telling others) that we need more of it.
