If you had to sum up what education's main principle should be in one sentence, how would you do it?

Dear Parent- I am writing to advise you that i have taken steps to stop the political bullshit, tearing down landmarks that people find offensive. I will be instructing the education department that any teachers who are offended by this letter i will be accepting their resignation as soon as possible. Finally I will instruct the education department being politically correct has now been abolished - Thanks Ned Kelly Education Minister
