Though the United States prides itself as being a nation of immigrants and the home of the brave, base appeals to the fear of immigrants and refugees has become a stock political tool. The use of this tool is, of course, neither new nor limited to the United States.
To be fair, there is some legitimacy to the fear expressed towards allowing in immigrants and refugees. This is because almost any large group of people will contain a certain percentage of potential murderers, rapists, thieves and terrorists. As such, allowing a significant number of people into a country will almost certainly result in some increase in misdeeds. Thus, it is not untrue to say that allowing in immigrants and refugees would increase the dangers faced by the citizens of a country.
While demagogues and pundits generally do not operate on the basis of consistently applied principles, restricting immigrants and refugees can be justified by using a principle. In this case, the principle would be that people should be banned from entering a country if their arrival would result in an increase in the dangers faced by the current citizens of that country. Since allowing a significant number of refugees and immigrants would almost certainly allow in at least some who would do harm, then this principle justifies such restrictions. While this does allow for a principled basis for restriction, it runs into an interesting problem if it is applied consistently. This sort of consistency problem is a common one—which is why demagogues and pundits generally loath and avoid consistency. This specific consistency problem is as follows.
Every country faces waves of immigrants that arrive unregulated and unchecked. While most of them are not a threat, a percentage of them engage in harmful acts ranging from minor thefts to mass shootings. Oddly enough, no politician has the courage to propose restrictions on these invaders and many actually encourage the arrival of more of these potential threats. I am, of course, speaking of immigrants from the womb. Each new generation includes a certain percentage of potential murderers, rapists, thieves and terrorists and thus presents a clear and present danger to the current citizens of the country. Using the same reasoning that justifies keeping out immigrants and refugees (that a certain percentage could present a threat), these invaders should be kept out of the country.
This suggestion should, of course, be greeted with snorts of derision and mockery: it would be absurd to impose a ban on such arrivals merely because some small percentage will become dangerous to the current citizens. The challenge is to reject restrictions on births despite the risk of allowing new potential criminals and terrorists to enter the country while insisting harsh restrictions or bans on immigrants and refugees on the basis of the slight risk they present is acceptable.
The most obvious approach is to point out that the potential rapists and terrorists who are born here are children of existing citizens and thus different from refugees and immigrants from other countries. This seems a bit unfair—where a person is born is entirely a matter of chance and is completely unearned. We do not, after all, earn or select our parents. Thus, restricting immigrants and refugees because some small percentage will present a threat while allowing unrestricted reproduction that will produce people that will present a threat seems to be grounded only in the vagaries of chance. If there is great concern about the threat presented by incoming people, then that threat must be addressed using the same standards on the pain of inconsistency.
It could be countered that immigrants and refugees present a greater threat: the percentage of murders, rapists and terrorists is higher among the vetted and reviewed immigrants than among Americans born here. However, this is clearly not the case. This should come as no surprise, given that the immigrants and refugees are vetted and checked very thoroughly by the United States. It is true, of course, that the system is not perfect—so some will slip through.
I might, at this point, be accused of wanting to impose restrictions on reproduction. This is not the case. My point is, rather, to show that the idea of putting harsh restrictions or imposing complete bans on immigrants and refugees because some tiny percentage might turn out to cause harm is as absurd as restricting or banning reproduction becomes some children will certainly grow up to be criminals or terrorists. This is not to say that there should not be screening of immigrants and refugees; there should be. After all, we generate so many domestic criminals and terrorists that it is sensible to try to avoid needlessly and carelessly importing more.
