Teaching isn't necessarily brainwash.
A good teacher could use these lessons to explain how our Rabies were biased and where we are biased as a result.
Fact is that most teachers just read whatever papers they were given on the subject. This is usually too boring to be effective brainwash.
By the way, we keep thinking that education ministers have this power over our children minds, and as a result they seem to think that whatever changes they make to the sylabus has this amazing power.
Truth is, that with the current quality of teachers, we are lucky if the kids learn anything at all, even things that can be memorized, not to mention delicate ideas such as democracy and religion.
