Censorship and Education What I believe is buried in your OP is the questioning of moral/ethical relativism.
Anything could be justified, but subjective justification is just that … subjective.
It makes perfect sense to pick what students learn and the order they learn it in. Does a pedagogical system necessarily have to be framed as ‘just’ or ‘unjust’. I think the idea of ‘justification’ tries to saddle education as something that takes place in a courtroom.
Just like with ‘offence’ a particular method of education is not at all compatible with every person at any age. As for ‘offence’ in education I would strongly insist that ‘upsetting’ students with ‘questions’ is something every teacher must do at some point so the student can learn how to deal with problems that rouse emotional responses in them. The difficulty faced by every teacher is picking and choosing where and when to ‘challenge’/‘offend’/‘question’ students … this inevitably leads to situations where students ate sometimes more ‘offended’ than challenged. It is dance between the student and the teacher, and consider that whilst the student has only to deal with one teacher at a time the teacher has to do this multiple times for a relatively poor wage and high stress.
This is just the tip of the iceberg … it is a very complex environment to work in and I have seen many teachers fall prey to being put into a position where they too often assume they are smarter than every student to the point that they feel scrutinsed unfairly if they make errors (which they will).
A classroom works well if there is a reasonably large and equal share of humility between teachers and students. A know-it-all teacher is perhaps far worse than a know-it-all student. If there is one thing a teacher should teach - not that I believe in ‘teaching’ per se - it is to teach students to question everything rather than cling to answers as an end goal.
An answer that cannot be applied to, or open up, more questions is not worth anything much at all.
