I can't help but feel like you've got a deep case of confirmation bias here.

This is true in anglophone countries, sure, but it's less the case in europe and in particular, say, eastern europe or the balkans: ignoring albania/kosovo/bosnia, you've got plenty of heavily christian countries there who are not so open to people of different ethnic groups (well, which deviate from ethnic groups common to the region). You'll be treated more or less well but still fundamentally considered an outsider, and may not be welcome depending on where you go. Consider otherwise the armenians who, while I'm heavily leaning on stereotypes, are still quite well known for being both 1. pretty deeply culturally christians, and 2. a pretty closed-off community that often intermarry (although I do know there's often intermarriages with greeks and georgians)

I would agree with your point, but I would warn you not to assume that everything true of americans and/or anglophone countries often follows closely in other christian countries.
