While there’s some truth to that, and MAGA Christians probably have some convoluted line of scriptural reasoning to support their anti-immigration stance, I would still hold that immigration/dealing with strangers is one topic where the entire Christian Bible (Old and New Testament) speaks with one very loud voice. Hospitality, welcoming strangers etc. are core virtues of a God-fearing life according to the Bible.

Which country are you from, if I may ask?
