I agree with you that most people who believe in souls identify with their souls rather than their brains, and it's not clear to me how any of what I said changes depending on whether people identify with their souls or their brains. But I'm also not strongly committed to this particular metaphor; if you have one you prefer, or have a different formulation of the argument in question you'd prefer to use that doesn't depend on metaphor at all, I'm happy to use that as well.
