In that case, I don't disagree on substance. But as a matter of clarity,

"It is only right to craft the law such that one's actions screen off the parameters of one's birth."

seems too casual for good communication; it's what a person would say who takes "right" and "wrong" to be simple ontologically basic properties of the universe.

On the other hand, the less misleading locutions I can think of would be pretty unwieldy in everyday conversation. I wonder if there's better language we can use or invent to talk about morality from this perspective...
