> divorce your identity from your beliefs about the world

I understand not totally subjugating your personal identity to ideology, but I'm struggling to see how someone could practically completely separate these two things. To use a somewhat trite but personal example, I'm gay, so that aspect of my identity will necessarily affect my perspective on certain issues. Conversely if someone were to convince me rationally that homosexuality was wrong, it would necessitate a pretty dramatic change of my identity no?

Not every issue exists on that clear a spectrum, but you can imagine the views necessitated by different pieces of personal identity adding up over a lifetime.
