In responding to criticism of the question, the journalist says that he's not anti-Israel (see here), and I have no reason to doubt that. He also notes, "everyone struggles with some thoughts on this matter":
Eden Golan brings risk and danger to Malmo as a singer of her beautiful country—even if it is a broadcasting competition. Crazy supporters of Hamas can take advantage of the situation and the interest in the [Eurovision Song Contest] for various activities. This was the question and nothing else
Here's my thinking: Of course someone has to consider the risk posed by the presence of people who are potential targets for attack—whether prominent Israelis, or Salman Rushdie, targets of crazed nonpolitical stalkers, or anyone else. It's the job of security people to consider those very risks, in deciding how to effectively protect the event (and I hope not in deciding to exclude the potential victim). And of course other people may indeed struggle with their own thoughts on this matter. Worry about risk of violence is a natural human reaction.
