I disagree completely, especially in the eyes of the law. If a comedian says he's going to kill someone, nobody is going to prosecute him. Threats have to be creditable. The tweets posted by Kurt all make some reference to his baseball career and then try to use that to make sexual jokes about his daughter. They are just terrible jokes and should be socially ostracized, but we should not be using the legal system to punish these kinds of tweets. The line is too unclear. None of the posted tweets contain any serious threat that doesn't contain some baseball innuendo, at least the ones Kurt published. There is a difference if someone said e.g. "I'm going to rape your daughter when she gets here" and that tweeter lives in the town of the school. One might be able to consider that creditable. We don't prosecute people who make others scared, we prosecute people that we believe have a creditable chance of harming another human being.
