Do you agree if I say it's wrong for answers to be valid only for U.S. standards?

It has often occurred that running across good questions I found that the answers were limited to things relevant to people/things in the U.S.
I’m not saying this is wrong. Only the rest of the world should be taken into consideration as well.

Of course my “flagfox” add-on for firefox says that Fluther is a U.S. site..
but being on the Internet it’s really available to users in the UK or Australia, Ireland, Mongolia, Egypt…etc..
It seems that most users are in fact in the U.S. , at least apparently so.
But shouldn’t, for instance examples given be presented with a wider, more global range, for all users to relate to?

Oh, by the way.. I live overseas (for those of you who do not know me).
