What are you, Spock? Outside of computer science logic has been used by philosophers for thousands of years to justify certain ethics. What, it doesn't count if you can't do a formal logic diagram? Absurd. Yes, racism is illogical, because it's based on unsubstantiated ideas (e.g. some race is bad at swimming) for which there's insufficient evidence, a given prejudice doesn't provide useful information because there's race wouldn't be a stronger correlator than other factors for a given prejudice (e.g. ability to swim). It requires confirmation bias and cherry picking to maintain. But leave that to the side, I'm happy to say "racism bad" is an axiom of human ethics, just like "slavery bad." I'm happy to simply eject the people that disagree from our society without the need to spend an ounce of energy proving them wrong or arguing with them. I fear the loss of nothing valuable in this circumstance. Is that dogmatic? Does it matter? Will you defend the racists and the slavers?
