Bravo Aupick! You have debunked more than a few false premises and conclusions free of logic. I just enjoyed a short tract by Henry Fowler, in which he adeptly skewered the enemies of the split infinitive. He praised--or was he condemning?--American preservation of grammatical forms which had, in the early twentieth century, become obsolete in BE. Was this saudade? I doubt it. Nor was it nostalgia, which is a rather different matter.
