Given the task definition and input, reply with output. In this task, you are given a public comment from online platforms. You are expected to classify the comment into two classes: identity-attack and non-identity-attack. Identity attack refers to anything rude or disrespectful about someone's identity, including appearance, race, gender, and sexual orientation.

Comment: Where do terrorists come from? Oh that's right, from Muslim countries! Let's welcome them with open arms so they feel welcome! <sarcasm off>
