It would have been more apparent that this was satirical for someone scanning if it had been surrounded by other Opinion articles on a page, and/or had a large political cartoon nearby. But these don't translate well to a deep link on a newspaper's website.
After reading this and the linked Boston Globe article, I had to come back to this page and look for "Opinion" (and found it in the URL before I found it on the web page itself).
But until then, I think there's a general feeling that the admissions process accepts those who basically only do "A" work, and subsequent grading within the school follows as such. Brown does P/F and Yale Law School omits grading too.
