"No one leaves home unless home is the mouth of a shark"
I'm not exactly sure what motivates people to oppose immigration, but I think a lot of their opposition is rooted in racism; racist stereotypes, and propaganda about the "ulterior motives" of immigrant to the US. At least in relatively recent years (the last century or so), there hasn't been a great public fear of white immigrants from European countries stealing jobs, rising crime rates, and creating the general "havoc" that many of these immigration opposers claim to be the root of their opposition. Somehow, none of those people stop to think about how most people immigrating out of their home country to the US or elsewhere, are fleeing some type of violence, military or personal, economic instability, or lack of freedom. My point is, as the title quote from Separated suggests, "no one leaves home unless home is the mouth of a shark," these people aren't fleeing their homes so that they can go create the same problems that they're running from somewhere else. And regardless of the supposed "risk factors" of accepting immigrants, crime, violence, dips in the economy, overpopulation, is all inevitable, even without granting safety to refugees in the process.
I think people are often afraid of anything that happens suddenly, occurs quickly and in great numbers. Immigration is a prime example of this, there are always people immigrating around the world, but it only gets the public's attention when something big happens. Most people, at least, don't spend their everyday lives worrying about the risks of increased immigration daily. It's only a "problem" when it catches us off guard. Although this wasn't included as a part of the prompt, I think that if the government spent more time working on organizing legal immigration processes, making immigration accessible, and just truly taking the time to figure out an organized immigration system, people would realize that the real "issue" with immigration isn't with immigrants themselves but with the unorganized, chaotic, and frankly just dangerous immigration happening, because these immigrants aren't left with another option.
In Separated, Meybelin and her father were trying to escape death threats in their hometown, they (like many others) went through hell and back attempting to get into the US illegally, and still, were detained and separated from each other. Deporting Meybelin's father, and later her as well after she had already spent almost a month alone living inhumanely in an immigration detention center. It's appaliing how obviously the US government cares more about preserving a reputation than the safety of other human beings, to the extent that they would go out of their way to separate and hold these families apart after everything they've been through already.
As Ms. Freeman mentioned, aside from folks indigenous to North America, the entirety of this countries population is immigrants, or those descended from immigrants. This country was literally built from the ground up to be a safe haven for people who couldn't stay in their homes any longer. The protestants who came over from England on the Mayflower were seeking religious freedom from Roman Catholicism back home. So why aren't those values upheld today? We know why, due to this countries history of prejudice, and false promises, but for that reason it is absurd to maintain that immigration needs to be "stopped" because these people "don't belong here," when this wasn't even our country to begin with.
