This is my last reply if you continue to present yourself in this manner.  Please write more civilly.

I expect people to go to Oyster Bay just as I expect them to go to Barre, Vermont.  When you type that, do you expect a disambiguation page or do you except the city?  Admittedly, it's not the most convenient, but that's the way it is in all eight "town" states.  Are you going to try to change every single community with this sort of disambiguation?  If so, go ahead — but unless you so desire, don't try to have one or two changed.  You speak of errors that result (for example, the Oyster Bay disambiguation page) — I do my best to fix wrong links as a result of changes such as this, but I don't see why I must be held responsible for every single wrong link.  If you never make mistakes, that's good; but I suspect that you so do.  So what?  It doesn't matter if you make a good-faith error, especially if you try to fix it once you realise that something's wrong.

By the way, if you put "Oyster Bay, New York" into the Census Bureau's Factfinder, you'll get this page: it's the town.  Barre, Vermont is similar to what we'd call a disambiguation page; the city is listed as Barre city, Vermont.  This, I expect, is the reason that these articles are named this way: the Census is our source for the names and the basic information, and therefore we entitle our articles likewise by this reliable source.
