From my view, race seems arbitrary. You could also split people into blue-eyed and brown-eyed or something. It still doesn't say anything about that person. Its just that many normal persons act like its a huge difference.
Show me a discrete situation where this results in bad decision making on my side, and I'll change my behavior.
You could pick any societal construct or experience and say it doesn't matter to you. That doesn't mean it doesn't exist.
You could say money is just paper and ones and zeros in a database so you shouldn't have to use it but you are deluding yourself.
Money justifies itself because it allows trade and therefore specialization of individuals. Its required for the technological progress we already done.
Same goes with Companies, Math, or most Science things.
Race is used by people who want to discriminate (independent of direction) or seek justification by victim-hood (and everything derived). Both are harmful behaviors. I will not support that.
