Equality is a fairly useless concept and elusive goal.
It doesn’t exist, nor is there any particular reason why it should. Equality in the chain of evolution is the end of evolution, as Darwin himself reluctantly admitted when it was pointed out to him. Blending of genes would blend down to sameness. Genes are not blended; they’re assorted, one or the other, digital, not a mixture of the two traits involved and selected. Mendel already knew the details long before there was even a theory to which it applied, like Reimann’s mathematics lying there in wait for a genius like Einstein to realize what it was good for, then buy it cheap wholesale and parcel it out piecemeal incorporated into cutting-edge physics. Equality in society and culture is no different. Ask the Soviets. When equality is enforced, evolution stops, and equality occurs on a level of poverty and dissipation for all. The issue of equal rights is the bone of contention and the bone we all fight over, a simple syllogism expanded from home to homeland, equal bathroom rights for all. Equality of rights and privileges in fact allows for differentials of accomplishment. Otherwise, forced social results demand unequal rights for their achievement, as in ‘affirmative action’ for racial desegregation in the US. It’s a thankless task.
