Though the United States prides itself as being a nation of immigrants and the home of the brave, appeals to the fear of immigrants and refugees is a dependable 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 of allowing in immigrants and refugees. This is because a large enough group of people will contain a percentage of potential wrongdoers. As such, allowing large numbers of people into a country will result in some increase in misdeeds just as a matter of statistics. Thus, it is not untrue to say that allowing in immigrants and refugees would increase the dangers faced by the citizens of a country. But this is analogous to saying that allowing anyone in your house increases your chance of being harmed. While true, it would be absurd to barricade yourself alone in your house out of fear that someone might present some danger.

While demagogues and pundits generally do not operate on consistently applied principles, restricting immigrants and refugees can be justified in a principled way. 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 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 a major problem if it is applied consistently. This consistency problem is common, 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 will engage in harmful acts ranging from minor thefts to mass shootings to bilking investors. Oddly enough, no politician has the courage to propose restrictions on these invaders, and many 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. 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 derision and mockery: it would be absurd to impose a ban on reproduction merely because some small percentage of people will become dangerous to the current citizens. The challenge is to reject restrictions on births while accepting restrictions on immigration while using the danger argument.

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. But this seems unfair as 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 who are 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 while kids are born with no vetting or review.  

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.
