> They seem to be one of those individuals who cannot possibly comprehend the idea that many people simply find murder and rape to be horrible, awful acts that shouldn't be inflicted on others

I’m not denying that some people feel that way. Feelings are real, they’re chemical signals in your brain in response to stimuli. But we agree it’s not more than a feeling, right? And nothing makes the chemical signals in your brain more legitimate than the ones in someone else’s brain? Say we gather up our tribe, clan, nation, whatever. We take a vote based on people’s feelings. And 40% feel like you do, and 60% feel rage at the neighboring tribe/clan/nation and want to violently conquer them and take their resources. We tallied up two sets of chemical signals, and we should pick the more numerous feeling, correct?
