What is untrue about that statement?
Besides that, it sounds pretty much par for the course in that era. Public schools treated kids pretty much the same. They certainly didn't do anything near what would occur in a common, ordinary Madrassa to this day.
Funny how quick some are to jump to the support of a newby who just signed up today. No need to check for veracity. Better to just like the allegation based on “who” the accused is.
