I would suggest you may be well read in certain areas, but not widely read. Blinkers are not an anachronism, and while Michaelmas may be less widely known than Christmas, it’s certainly still celebrated.

Agreed. The OP's declaration that this is a difficult read pretty much proves the point of the article.

Especially if you were entering university as an English major, it seems like table stakes to have a conceptual understanding that not all English is going to be in simple, modern terms. That is you're going to be reading books from a variety of time periods and cultural origins, you might need to develop an understanding of those sources.
