Samaritans were still isreallites, though. Just not “Jews”- different tribe. And there were some tensions there- but the law requiring hospitality and kindness to each other still applied.

Jesus was perfectly okay with enslaving non-Israelites, however. And also stonning unruly children.

Is it really a surprise to find that christians sometimes turn into assholes?

A lot of the southern evangelicals here lean into the asshole side than they do the “we should be nice” side.
