Correction, I never said "0% chance of committing a crime." I just take exception to the argument of "illegal immigrants commit crimes at lower rates than the native population" because it's misleading. You're not doing anything to assuage the fears of your countrymen who don't want more crime in their area. When you have a neighborhood with low crime rate, higher crime rate illegal immigrants start coming in, and the natives say "we don't want these people here because crime," it's disingenuous to call their concerns false or irrational because the newcomers are not as criminal as inner-city Chicago. You have real people, victims of real crimes, from real criminals who shouldn't be in the country because the citizens passed laws to keep them out, and when they complain you call them names and try to justify your lack of concern by willfully misreading statistics.
You have real countrymen, with real concerns, and you just don't care. I don't think you have any great love for the illegal immigrants, as I doubt you'd live in a neighborhood with them. You just want to inflict them on others who make the same rational decision you do, but can't afford to move away. Again, I think you just hate your countrymen, because there's no rational reason to deny them the police protection of their own government except for malice on your part.
It's somewhat similar to, but even more unfair than, Israel's immigration laws that allow much easier paths to citizenship for people who are Jewish by faith and/or ethnicity.
But what else are you supposed to do if you're a Jew who wants to live with other Jews so you don't have to put up with gentile bullshit?
Is it immoral for the Japanese to not take in immigrants? It's practically impossible to immigrate to Japan. But I don't think Japan would still be Japan if they suddenly took in 30 million white people or 30 million Australian aborigines.
In the long term, do you think multiculturalism will be stable? Americans for the past few decades have spent enormous resources (both economically and culturally) to try to integrate their society. Educational programs, television stereotype programming, student codes of conduct at universities, anti-discrimination rules in the HR departments in our workplaces, "hate speech" censorship on our social media platforms, etc, and yet polls show a great number of Americans (especially black Americans) think race relations are in the toilet. What hope is there that increasing the diversity of the US will make people get along better rather than worse?
