"WWJD?" Cute. But you're an atheist. You don't believe Jesus was divine, you don't believe the Bible is true, and you don't accept religious authority on anything else. So why do you try to use my morals against me? You reject Christianity 364 days a year until it conveniently backs your open-borders welfare stance, then it's 'WWJD?' Pick a lane.
Even if we humor your biblical cosplay for a second: Jesus never once told the Roman government to tax citizens and hand out free stuff to non-citizens. He never lobbied Caesar for expanded welfare programs. He preached personal, voluntary charity - sell your cloak and give to the poor yourself, help the stranger you personally encounter (Good Samaritan was one guy on the road, not a federal entitlement program). He fed the 5,000 with a miracle, not by raiding the treasury. The early church helped widows, orphans, and travelers out of their own pockets, not by forcing non-believers to fund it at gunpoint.
The actual social contract in a secular democracy is simple: Citizens pay taxes because they consent (via voting and the Constitution) to a system for themselves and their posterity. Non-citizens aren't part of that contract. They didn't fight in our wars, didn't build the infrastructure, didn't vote for the welfare state. Giving them automatic access to citizen-funded benefits is just theft by ballot. Take money from people who did consent and giving it to people who didn't. Private charity, churches, and voluntary organizations can (and do) help foreigners all day long. That's the Jesus model if you're into that. Government welfare isn't.
If your real argument is 'compassion requires open taxpayer-funded spigot for anyone who crosses the border,' then own the secular version: unlimited incentives create unlimited migration, bankrupt the system, and punish the actual citizens who built it. Jesus helped individuals. He didn't destroy the village to save the stranger.
I ask again: why should a non citizen be given free lunch?
If you want to invoke Jesus, then we can pivot the conversation to abortion and ensure you're consistent in your newfound love of Christ
