Does referring to it as The Terrorist state of Israel constitute an Epithet or Slur??
No it is not offensive and you should protest that violation. You are well within your rights to call Israel a terrorist state based on the actions of the country since its conception. I hope you do not just accept this violation. This is no way an epithet or a slur, you are merely stating your opinion. Unless for some reason the country of Israel itself, turned into a person capable of using Yahoo Answers and is now asking and answering questions, then maybe they could be offended. In reality it was probably just someone who was offended by it and was like ohh that is so wrong.
