Somebody wrote, with a scolding tone, something along the lines that "You may not realize this, but "Chinatowns" are proper historical and cultural landmarks."

Hello?

Um, that kind of skates around and ignores what the other post writers are getting at, doesn't it?

I mean, it is pretty easy to look around big Canadian cities and see where, over a hundred years, the WASP or Catholic Anglo/French neighbourhoods got replaced by a Portuguese neighbourhood or a Greek neighbourhood or an Italian or a Hong Kong neighbourhood, and where some of the latter neighbourhoods then got replaced by a Hungarian neighbourhood or an African/Caribbean neighbourhood or a mainland China nieghbourhood or whatever. 

I think what some post writers are getting at, the subject avoided by the scolding post, is why do so many folks (the media, the politicians, the activists) are okay with the noted changes over time for MOST neighbourhoods but then raise a fuss of protest over a place called Chinatown...
