Well, if you replace the star with a pin that says "I support political violence", then yes, you SHOULD wear it. Just so anyone around you knows you cheered for a murderer, so they can protect their kids from you. You want someone who cheers for the murder of people they disagree with to teach a class full of kids? To operate as a doctor? To work as a police agent or a firefighter? To work at the FBI, CIA, or any such organization? To work as a member of the Secret Service?
