“Reason” and “morals” are unfortunately not synonymous :(

If your morals say that killing to reduce the costs of accommodating disabilities is okay then your reason will dictate you start killing people in wheelchairs.

This is honestly why I feel like us liberals fail so often: you can’t reason someone out of a position they didn’t reason themselves into. The position “white people are superior” - the starting point from which many of these heinous behaviors begin - isn’t about logic and reason. So trying to use logic and reason to explain why killing minorities is bad won’t work. We act like if we could just explain how unreasonable they’re being everything would be okay. But that’s not how it works.

You have to address the rotten foundations first. Otherwise they will continue to spout off what sounds like reason if you just accepted their premise.

Reject the premise, not the logic used to get from the premise to the behavior

They probably mean secession, but don’t understand the reasoning behind the secession.
