Both lead to a bigger, more intrusive and powerful State. It can’t be any other way. Supporting either is supporting this bigger, more intrusive and powerful State. For “pragmatic” reasons, I suppose.
It’s not that I support “open borders”; it’s that I recognize no borders other than private property lines–all other “borders” violate private property. Government’s “borders” are a violation of YOUR private property and right of association, as is government’s plan to import “refugees” or anyone else.
Government screws up anything it gets involved in, and I don’t support anything it does. Don’t help it by begging for it to do anything on your behalf. It won’t go anything like you imagine.
