Well, sure, but rather than get into a shouting match, I’ve compiled a list of suggestions, drawn from various sources, like this, from The Dot, and this, from The Seattle Globalist, and this, from Baltimore Racial Justice Action.
In short:
- Get educated
- Prepare for defensiveness
- Stay calm
- Be personal
- Understand that racism can be subtle
- You will probably fail the first few times out
What else? What am I missing?

Mentioned in 2 of your sources, (the third wasn’t really about what to do but what not to do).
Clarify
Make sure you clearly understand what you’re hearing.
As for me, I would try not to make it personal in order to avoid defensive posturing.
