teacher are having less choice because a few bad eggs have been doing more than using a bit of freedom to teach, they've been abusing it, for some things they need strict totalitarian soul crushing stranglehold. 'it's just a theory' instant suspension. give them too much freedom and it's 'and on this glorious day, as we await the return of our dear ravenous hastur, we now learn these unimportant things to comfort us while we await the fulfilment of our true goal, feeding our lord' totally allowed if other religions get to do it. the freedom to teach what is important at that time doesn't trump teaching properly. what this girl is talking about is teachers that legitimately don't care, at all, and react like a teased dog when the truth gets pointed out, in other words, teachers abusing their freedoms.
