Late email, from a reader:

Hi Jonah, just to add my 2 cents, ‘technically’ your previous reader is incorrect. The word for school in Indonesian is ‘sekolah’ not madrassa. Madrassa is an arabic word. I lived in Indonesia for 3 years and never ever heard a school referred to in arabic i.e. as a madrassa. As you point out, the usage of the arabic version is inaccurate, misleading, and part of a hit piece. You were right the first time.
