 This is obviously dumb and people treat this like a joke, but if her culture was consistent they would have no problem with this. For years they've trumpeted the philosophy that you can identify as anything that you want to identify as and you don't need to be constrained to the social construction of what you were born into. But here's the thing, we can't choose our identity. You are either male or you're female. You're either a child of wrath or you're a child of God. What we choose to identify as doesn't change reality. Our gendered identities as men and women aren't a mistake, actually they're ordained by God. Our identity of being a slave to sin is actually counter to God's good design but we can't change it on our own. But through Christ's payment on the cross we can receive a new identity in Christ and be freed from sin and be made alive to Christ.
