As a teacher, there are two basic ways to present anything.
1) "This is X, and I am going to give you some FACTS and tell you what I THINK X is. Then you can make up your OWN minds whether I am right and what your attitude towards it is."
2) "This is X, and I am going to tell you what X is and/or means and what you should think about it."
Approach 1 is morally and intellectually honest and ethical; approach 2 is the opposite except when pure FACTS are the topic. It seems to me that the girls' school above is adopting approach TWO. Incidentally, is it STILL going to call itself "a girls' school"? If not, then WHAT?
TOO MUCH education is done according to strategy 2) (which of course is indoctrination) - and the same applies to the NEWS, especially the BBC and Establishment-distributed information - and in "faith schools" and under dictatorships of course.
I read "1984" at WHS, and since then have had an absolute horror of indoctrination and being told what to think. I do not feel that WHS teachers ever told me what to think, except of course when it came to bald facts such as "Chisinau is the capital of Moldova." or "The chemical formula for water is H²0."
