This article struck me as ignorant enough that I gave up before it got to the history, which may have been interesting. Every language has things unique about it, otherwise it wouldn't be considered a different language. Picking a couple from English (some of which are really arbitrary, others not even true) proves nothing.

Yes, English has some unique features. But rather than every English speaker going around thinking their language is some massive exception, I'd like people to understand that English has been subject to essentially the same forces as every other language, and makes plenty of sense given the history of Britain. But I think many of us anglophones want to hold on to a sense of uniqueness rather than acknowledge our commonality with the rest of humanity.
