I don't recall Jesus predicating "love your neighbor as you love yourself" with "
as long as that neighbor is legally within the arbitrary bounds of the nation-state that exists in the time period in which you live."
Since you all also like to go back to the Old Testament when it suits you to justify your actions as being because of your 'religious beliefs',
Leviticus is pretty clear in what says about how you should treat foreigners in your lands.
'
And if a stranger dwells with you in your land, you shall not mistreat him. 34 The stranger who dwells among you shall be to you as [a]one born among you, and you shall love him as yourself; for you were strangers in the land of Egypt: I am the Lord your God.'
Ah, so allowing the government to deport illegals is unloving? I can't feed them, help them, etc while also understanding the need for closed borders and immigration laws in the US? That's odd, as I've actually participated in ministries that help immigrants (many who are illegal) with food, clothes, childcare, etc. And I simultaneously believe that legal immigration is important and that deporting illegal immigrants is ethical, by and large.
Let's think wider about what it is to love
all of our neighbors? The ones murdered by undocumented illegal aliens because they weren't vetted? The ones who wanted to come here through the legal processes but instead watched illegal immigrants break the law to cut in line and take their place, and watched the last administration urinate on their time, efforts and money by releasing innumerable illegal aliens in? The ones who are victims of identity theft?
If I have three spare bedrooms in my house, you may call it unloving to lock my doors and be particular about who I invite in to sleep there, and how I make such decisions. That is, until I unlock the doors and my house becomes an overrun crack house that's of no use to anyone.
Perhaps it's loving to manage my home well so that I can continue to be able to help those that I can help with my limited resources. Legal immigration is one important mechanism by which our country keeps itself healthy enough to help whose whom we can help.
(And you were quoting a verse that was directed to Israel at that time and place. One important hermeneutic rule entails understanding the context of who it was to and why it was given. You'll note that Christians are not Jews living in ancient Israel. We are Christians living in secular nations, who are commanded to respect our government and its laws, respecting their authority as granted by God, and their "sword" as God's tool to bring fear against lawlessness. I notice you aren't begging Christians to stone homosexuals and prostitutes. You should probably appreciate that hermeneutic rule.)
I am happy to discuss this with you, but your flat, shallow interpretations, used merely to try to shame people into agreeing with you, will need to change.
