Every nation has its adherents who point with equal justification to their best bits. For example, a long sojourn in Brussels has taught me just how appalling UK chips are: they're a studied science in Belgium. Yet Al loves them. Perhaps both are right. Chips aren't fritjes, and they aren't frites, and frites aren't French Fries, let alone matchstick Freedom Fries.
There are parts of Breughel's Pajottenland which entirely rival Constable's Flatford, and...well, my point is that the list is long, and all it means is we're parochial and should find companionship with the others who find the same elsewhere. Which is rather an argument against this kind of Flanders and Swann Patriotism: to claim otherwise is simply a sign you've not looked elsewhere to find the same.
