Deletion of List of American words not widely used in the United Kingdom

Comment: while for the moment I sit on the fence) - if this article is deleted, then List of British words not widely used in the United States must also go. These two articles need to be considered together. In favour of '''keeping''' them: There surely is a core of words that are distinctively American-and-not-British, and vice versa, and it is perfectly possible to back up a list of such words with reference to various sources. I utterly reject the nominator's ageism|ageist reasons for deleting, and the nonsense that British culture is American culture. And yet there are also reasons to '''delete''': This pair of articles are extremely |useful, utterly |fascinating, and a great deal of |work has gone into creating and maintaining them - but all our time would be better spent helping to improve the more general information at American and British English differences. The two lists are constantly liable to degrade into unreliable and misleading uselessness, attracting a fantastic quantity of original research and unfounded personal opinion. The problem is the list structure, which acts as an invitation to add "my two-cents-worth" or "my tuppence-worth". The more discursive article on American and British English differences is far more valuable
