Ok so how should I know what will damage another person if it it seems non threatening to me. Also that like saying what some stupid teachers in my school say,I made a deaf joke once and the teacher got mad because they said that one student could have a deaf family member and get offended. Thats plain stupid, when my grandpa died 1 year ago if someone made a joke about a grandpa being dead and not knowning my situation I wouldnt get offended and I believe its stupid if someone else got offended.
