Fairness is a Torah value. Equality in the eyes of the law is but one application of this concept.
If one person is drowning, this does not mean that everyone in the pool should get cpr.
The commonly accepted conception of equality that the rose bush and the cedar tree must both be of the same height, color and build is a mistake that has had terrible consequences for western society.
The Torah teaches us to recognize and celebrate our different roles in Hashem’s world.
