When my son was born a few months ago, the nurse came in to review his blood type with us, and I had a moment of realization, and/or thankfulness that such a trivial difference isn't a reason to treat him differently than myself, or my wife, or my daughter. 

It made me think with a different perspective. I imagined what it would be like if they came in the room and said my son would have a different level of opportunity, or would be treated differently than his sister because they were different blood types. Or that he would be treated differently in school because he acquired a certain type.   

Skin color is just as trivial. The divide and friction caused by something that shouldn't even be a topic of discussion is astonishing. 

It is not someone's choice how they are born. What color skin, what blood type. 

It is, however, a choice how they will treat others.
