Cultural and identity death of a country is in my mind a valid threat.
Does it scare you at all that someday, you'll wake up and be the tribal grandpa? The one who people dread to invite to Thanksgiving dinner because you drop comments like these?
People say this stuff literally every single time that a western nation gets a wave of immigration. They did it with blacks, they did it with the Germans/Irish, they did it with Hispanics, and they did it with the Chinese. All of these groups, despite cultural differences, have managed to find their own ways to assimilate into our society. The exact argument about 'refusal to assimilate' and 'death of culture/identity' has been used
every single time immigrants show up in history, and it is always wrong. Statistically speaking, it was probably used against your own ancestors at one point in time. And yet every single time, it's bullstuff.
Nobody's culture and identity is dying. If you want to eat pork and worship Jesus, you will always be able to do that in the United States. But what won't stand is letting people be subjugated solely because of their religion or race. If that's the 'cultural identity' you want to protect, then I hope we kill the stuff out of it.
also I'll take a billion-dollar wall that may or may not work over a financially impossible system that would crash day one thank you
For what it's worth, it's 100% true that socialism and communism are broken economic systems that can't work. But Sanders-style socialism isn't socialism in the real sense of the word. It's public control over key industries which don't really work well enough when governed by market principles. We've done this in the past and it hasn't caused our government to collapse a-la Venezuela.
