That doesn't sit right with me. It sounds to me, in that moment, like they're implying that people from other cultures could be less moral, and that we should be willing to be more free with our weapons towards such people.

This is, unfortunately, how many, many very religious people think. And it's not only insulting for everyone not following their beliefs, but also terrifying in my opinion.

People who believe their god is the only thing that makes them moral aren't really moral. Because then they never consider why it's important to, you know, not be an asshole. It's just compliance.

And the terrifying part is that since their only frame of reference regarding what "good" is would be whatever their religion dictates, it's always on the verge of breaking completely. You just need to listen to the wrong interpretation at the wrong moment in your life.
