The problem with your conclusion is that it eventually becomes meaningless. If everything is racist, then nothing is - and all meaningful discussion becomes irrelevant.

Why would we think about voting rules and poll tax by the back door (definitely racist) if it must be given equal weighting and consideration with the cast of Bridgerton and/or whether soap dispensers in college campuses are racist.

The conclusion that everything is racist does nothing to solve the problem of racism - it simply encourages a game of race based bingo where a new thing is discovered which may or may not be more impactful a discussion. You'll just keep finding racism and never learning anything or implementing a solution. The dialogue must move back into meaningful areas where progress can be achieved - and that isn't found in the field of microaggressions etc, it's found in systemic economic change and social projects.

The work you're instructing white people to do and doing yourself will be never ending - and as that work would be never ending, it would also be pointless. Because it would grow increasingly pointless, not doing it would be racist, but have no fear - so would doing it. When everything is racist, including your original article - and my subsequent comment to your article - the goal of eradicating racism cannot be achieved.

But also, I enjoyed your article you racist ;o)
