White people, stop asking "what should I do?" to fight racial injustice. Start asking "Who do I want to be?"
Go about answering that question until you figure it out. That might take minutes or hours or days or weeks or months or years or longer.
However long it takes, commit to figuring it out. Commit to embodying immovable values and principles that guide your thinking and action and decision making.
Identify what you believe in, what you will not stand for, what behaviors you will and will not tolerate—from yourself and others.
Articulate to the world what is and is not okay for you. Proclaim it with confidence. Declare it with conviction. Shout it to anyone and everyone, whether they are listening or not.
Be consistent and constant. Establish your views, your perspectives, your belief system. Become known for what you care about. Become unapologetic. Become defiant.
Absorb doubt. Absorb criticism. Absorb attacks. Absorb dismissal. Absorb character assassination.
Don't waffle. Don't hide. Don't run away. Don't retreat. Don't devolve into your comfortable habits of privilege.
Use your power for good. Use your social capital to uplift. Use your voice to amplify the unamplified.
Commit to becoming who you are meant to be. Then you'll have no problem knowing "what to do."
