If we're gonna start debating "Americanisms", I have to say that I use a fair mixture of "British English" and "American English" by choice.
For example, I prefer "elevator" to "lift" for the following reason:
It's called an Elevator because it elevates you (the fact that it can descend as well as ascend, is a whole can of worms best saved for another discussion)
Therefore surely "lift" is what it DOES, so the noun should actually be "Lifter"? (e.g. "I'm going to go to the 8th floor, in the lifter") Of course, nobody in their right mind is actually gonna say that, BUT I still object to it being "a lift" because I personally think that that's contextually b*ll*cks. Therefore, using the American "Elevator" is the only realistic way of me satisfying what I think is logical.
Also, coming as I do from Warwickshire (which I think is probably one of the most absolutely central counties of ENGLAND (if not THE most central)), I think that "my kind of English" ("Warwickshire English" if you will) is the most "universal" (i.e. not TOO "southern/Queen's English-y" or "northern" etc), but is one of the most even-handed mixtures of the best of all variants.
I despise with a passion the "Queen's English" way of pronoucing words like Bath and Grass - I pronounce them with a short sharp "a", rather than an "a" that sounds like it's got an imaginary "r" after it.
Seeing as "Queen's English" is surely spoken, say, no further north than Hertfordshire, and no further west than Hampshire (or whatever), it is effectively a "REGIONAL accent" (I call it "South East English")???
Although in POPULATION terms, more Brits speak "Queen's" than those who don't, GEOGRAPHICALLY they're a "minority".
I like the fact that it seems to be the case that the further north you are in England, the more "literal" the pronunciation (e.g. Yorkshire etc pronoucing Book and Look to rhyme with the "oo" in "Spoon" - which makes a damn sight more sense! "Northern English" is, in this respect, the most "logical" IMHO. (If it's got an "oo" in it, why the flip should it be pronouced "buck"???)
However, although my PRINCIPLES agree with a "Yorkshire" Look or Book, it would sound unbecoming without the appropriate accent to accompany it, so I do indeed say "luck" and "buck".
These are just a few examples, but they illustrate how my speaking habits are where "northern" and "southern" meet, and I'm even broad-minded enough to encompass Americanisms, Australianism etc etc.
Too many English-speakers are too insular re: not tolerationg anything beyond their individual version. The "Queen's" speakers are the absolute worst, for having an intolerent attitude towards the rest of us.
I'm really really proud of "MY" version of English.
