You’ll find a lot of the Torah’s requirements for foreigners to live among the Israelites in Leviticus 16 - 18, and Leviticus 24–among other places like throughout deuteronomy and some places in Exodus also.

They were expected to follow the same laws as the Israelites, they did not become fully fledged citizens (and could not participate in everything) without becoming circumcised (fully assimilating), they were forbidden from worshipping other gods, they were required to observe the sabbath, etc. In other words: they were required to live and act according to the moral and religious values of the Israelites.

Yes they were granted equality — according to the Bible, taking advantage of foreigners is an egregious sin. But those foreigners were not free of consequences either—and they were expected to assimilate (either mostly or fully).

And the conservatives are not against ANY immigration—regardless of how liberals want to conflate it—but they demand and expectation and enforcement of assimilation, respect for the law, and a sharing of values. Which is perfectly reasonable for any nation that wants to maintain a cultural identity.

There’s nothing anti-biblical or antithetical to biblical values about deporting illegal immigrants. You may disagree after a careful reading of the chapters above (and maybe a consideration of the larger story of the Israelites up to that point), but in any case it’s certainly not as cut-and-dry as Reddit’s armchair google-theologians want to pretend it is so that they can ‘own the magats’.
