There are some truths but many problems with this post IMO
I have written a response here https://elliottjohnreid.medium.com/all-people-are-racist-at-first-b38e072ac385
The statement "all white people are racist" is less true than "all people are racist". There is a deepwired response to those who appear to be from faraway lands. But this should be unlearnt as it is in many children and arguably less adults.
The other issue the question of as to whether or not this rhetoric promotes a people to move forward or to squablle right where they are whilst making no progression.
I would be interested in your thoughts
