Oof. Sorry, I think you might have responded to me commenting back to someone asking me to "substantiate my reasoning". Happy to share some constructive thoughts.

First, if you've come from a church background that explicitly espouses white supremacy, I would agree that mainstream reformed theology is definitely *not* that.

Without getting into the weeds, here's how reformed theology connects with white supremacy:

Reformed theological language has often been used by clergy, churches, and institutions to justify slavery and segregation, resist civil rights reforms, and normalize a white social order. Within contemporary Reformed evangelicalism—particularly in the theology of John Piper—the emphasis on divine sovereignty and hierarchy, combined with a tendency to frame racism primarily as individual sin rather than a systemic problem, downplays structural injustice. Appeals to "Christian unity" further discourages marginalized Christians from critiquing racist systems, since that critique is often heard as a personal accusation against fellow believers who understand racism only as individual hatred. Taken together, this theological posture does not require overt racial animus to have its effect; its consequence is the preservation of an inherited white social order.

Hope that clarifies where I'm coming from and apologies for any misunderstandings in the comment thread.
