Yes, angrily. It's a channel that somewhat rewards anger, too, since the nasty tweet probably has a whole bunch of other people who "kind of wanted to say that" who will retweet and like, since it lets them get in on the screed without feeling fully guilty of saying it themselves. And you know how it is with these things, when you see anything you wrote get retweeted a ton or liked a ton, it gives you that kind of thrill. So the angry voice gets a bunch of positive reinforcement.
