Actually, leaving aside the specific situation we're dealing with in this thread, when it comes to the broader argument about "heritage", I'd reckon that even the sensitive European heritage realm would laugh in your face. It's like you're suggesting they'd scoff at Mount Forest because it's not Montparnasse. Look: there's a universality to "heritage sensitivity"--it covers the ancient, the medieval, and the seemingly-unimportant-by-comparison recent past--and not only in North America in the latter case, given how even Europe recognizes and respects its c20 heritage these days. And yes, that includes commie blocks from the 1960s, etc.
OTOH, your attitude might well have more in common with those from those apparently more "heritage-rich" lands who move to Canada to, well, *escape* the kinds of strictures they identify with their teeming-with-heritage homelands; that is, by opting for a land of comparative unregulated freedom with, in their eyes, negligible fare that's of "historical importance". And rather paradoxically, they're prone to using the "we come from a land of rich history" alibi to excuse their own philistine insensitivity.
So, get this straight. The "most other people" you're speaking of isn't the heart of the heritage realm; in fact, they're probably more Sunday-painter amateurish in their scoffing than those they are scoffing at. Especially if you consider that those they're scoffing at are not "heritage or bust" absolutists even in this loaded case, but simply allowing for a valid heritage argument as part of the overall dialogue--believe you me, it'd be no different in Europe, however much you protesteth otherwise...
