Now, should we have borders? Borders can be justified on utilitarian grounds because they allow a state to impose laws, provide safety, and control a market. But borders split people and therefore create a relationship between them. And that relationship can have moral and historical dimensions. For example, if a country has caused harm to another in the past, there would be a moral responsibility to rectify that wrong. The argument that the West should let in refugees is predicated on the West's history of colonialism and military adventures in the third world. Note that this moral-historical point of view is in opposition with the utilitarian case for borders. And this is where the author of the article and you disagree, and the point at which the battle for refugees is being fought.
