If someone says it's your job as a person with privilege to dismantle systems of oppression, instead of panicking and getting defensive, you can do one or both things

1. You can just say "I don't know how to do that." Seriously. I think so much of these lame ass comments are because people panic and get defensive. And instead of just being honest, they try to intellectualize their way out of the anxiety.

2. Literally go google "Black activist authors" or "queer activist authors" and learn.
