Illiberal Immigrants and Liberalism's Commitment to its Own Demise

Can a liberal state exclude illiberal immigrants in order to preserve its liberal status? Hrishikesh Joshi has argued that liberalism cannot require a commitment to open borders because this would entail that liberalism is committed to its own demise in circumstances in which many illiberal immigrants aim to immigrate into a liberal society. I argue that liberalism is committed to its own demise in certain circumstances, but that this is not as bad as it may appear. Liberalism’s commitment to its own demise is merely a reflection of the fact that it must take into account the rights of outsiders, not just the rights of existing citizens, and of the fact that circumstances of injustice can sometimes leave liberal societies with no correct choice.
