In 2018 I published a book called The Virtue of Nationalism. If you give up the word nationalism, the problem is there is no substitute for that word. You simply erase the political theory I just described because there is no other word for it. It doesn't just say I love my country; nationalism means I also make space for my neighbors to love their country. That's the reason that a border between us is a useful thing because good borders make good neighbors.
