Good. If I can 'identify' as anything I choose, then there is no rule of law. It opens the door to pedophilia, racism, to name a couple, and a myriad of demands to the govt for special treatment.
Of course the govt will want to pick and choose, and not apply the concept of 'identity' equally, violating it's own proclaimed upholding of equal protection, while morally playing the church as well as state.
