I agree with everything you said.
However, Japan does not censor literature, neither does she censor the internet ( unlike China ).
Any honest Japanese bent on knowing the truth can find out about it.
True enough, SeekAndFind, a Chinese-like censorship does not exist there but there are other kinds.. Even here in this country. Let an American college student in a History class speak about the Democrat party and its relationship to Jim Crow, the KKK, and the fight against the Civil Rights movement and he or she can watch their GPA plummet and they could consider themselves lucky if they are only kicked out of the class and not the institution itself! Japanese institutions of learning don’t like upstarts, either.
