Welcome!
Gifted children are known for having a high level of moral sensitivity.
Here is a link to one of many articles on the topic:

One idea for home discussion may be to present concepts by analogy:
- golf "handicap"
- standing on various steps of a stepstool or stepladder to reach the height needed to see over a fence
- using a scale, placing an object on it, then re-calibrating it's weight to zero (for example, to measure contents of package, without the weight of the packaging)
Layered upon that, one could discuss:
- whether the golf "handicap" is current and valid
- whether a person's height indicated they had outgrown their assigned step on the stepstool or stepladder
- whether the packaging weight is consistent, or whether the amount of weight attributed to the contents may be inaccurate
The concepts of mistakes made without sufficient knowledge, wrongdoing when one ought to have known better, taking responsibility for one's actions, apologizing, and forgiveness may also lend perspective and guide his understanding and analysis of situations he may encounter at school or in other circumstances outside of the home.
When presenting facts from history in the home, one may also want to teach the history of the US Constitution and its amendments. It is still the supreme law of the land, and its 14th amendment contains the "Equal Protections" clause. Under US law, people have been treated as individuals, not as demographic statistical groups; are there signs that the manner is which the law is applied may be changing?
Considering the concept of ensuring "equal opportunity" as compared and contrasted with ensuring "equal outcomes" might also be discussed alongside finding the strengths in our differences such as height: Being tall is an advantage in basketball... is it an UNFAIR advantage...?
