Sympathy is dead to governments and most businesses. Especially with the nationalist opinion gaining popularity recently, I would expect sympathy for the fellow human if they're from a different country to die down even more.
Oh please. You don't know your history then.
We also refused Irish during the Potato Famine. This time it was because they weren't "healthy" - aka, no damn Mics.
After a campaign of anti-Irish sentiment, the Italians came here. We have a racial slur for them - fops. They were turned out en masse.
We denied the Jews coming here in '36. Didn't like Jewish - they kill and eat children! (Yes, this is in the US National Holocaust Museum as example of propaganda.)
We denied the Jews again in '46, AFTER knowing the atrocities they suffered in Europe. You know, those damned Jews.
In the 50's, we laid heavily into the Slavic and Baltic countries... Those damned Commies. Oh you were leaving because of humanitarian crisis? LIAR.
That's just a few examples. This whole Muslim ban has been done before with nations, politics, and religion (Irish, Communist/Socialist, Jewish respectively). Most populist "leaders" will garner support by singling one group out and attacking. Just like Hitler did, and following in the footsteps, Trump.
When I was a kid we used to cross the river into Mexico to go eat (on hunting trips near the border). We'd pay a guy to row us across and then back. It was a well known thing. People from both sides used it to go back and forth all the time.
Guess what, now that guy in a row boat is an official US border patrol checkpoint. LOL
The border is a big joke.
I doubt it. If you really wanted to deny border crossing, you'd have to allocate so much money to ICE that it would upend the federdal spending budget. It isn't feasible easily. That would make the current administration look stupider that it already is.
Good and Bad are definitely subjective. Illegal immigration is good for the illegal immigrant because they have better quality of life. Millions of Americans who voted for Trump seem to think it is bad. So it is definitely about perspective, and the reason we bother to make labels is because we live in a civil society where we follow rules, no matter if some people don't feel it is necessary.
