Combine it with Hume's Guillotine and you realize that all "should" conclusions really just start with moral "value" axioms. So then you can make a distinction between people that reason correctly from values that are different than yours, and people that reason badly from their axioms. And you can also make a distinction between philosophies that are based off of unprovable beliefs (which is fine), and philosophies that are anti-factual (which isn't). I like to define the former as religion and the latter as ignorance, but unfortunately there are a lot of the latter that claim it's religion.
