If you use the right language to talk shit about someone no one can ask if you are lying. No one can question the harm you are doing. Use the right words to do harm and you don’t need to think about where the hurt comes from or why you have chosen that person to project it onto.
Appropriate the right terms for who that person is and you can justify every punishment, every act of cruelty and exclusion. With the right words you grant permission to erase their complexity, nullify their words and experiences, reduce them down to evil. Use the right words and nothing is on you.
Now you can point fingers. You can kick people out. You can seek revenge. Catharsis. Temporary relief followed by devastating relapse. Your sorrow is still there, the deep pain is still there. And those right words have done nothing but caused more harm.
