BTW, not that it matters, but your definition of censorship is slightly askew. There is government censorship, but that does not define the concept of censorship generally.
A teacher can censor class discussions for example. (and they frequently do)
Inflected Form(s): cen·sored; cen·sor·ing /'sen(t)-s&-ri[ng], 'sen(t)s-ri[ng]/ : to examine in order to suppress or delete anything considered objectionable ; also : to suppress or delete as objectionable
I was speaking culturally about censorship, not in a merely book sense.
