Aiding and abetting terrorists can be and is punished. Sympathy for IS or similar groups/countries is a whole different story. As long as they are at best voicing their support, or not even that, it's really difficult and contra-productive to prosecute. If you want to morally condemn every Muslim for sympathizing with IS, you should keep in mind that most people fighting them are Muslim. You also should keep in mind that most Muslims don't sympathize with these kind of crimes or terrorism in general....
