egads, do you seriously believe this? Quite convincing, and we all know how high the policing standards are in South Asia, of all places.
Oh, it's not a 'thought terminating cliché'. Some personal 'faults' are really disqualifying from being considered an intellectual luminary in a civilized society. Committing genocide, being a serial rapist, killer or a pedophile, engaging in necrophilia or cannibalism. At the very least, these traits should always be mentioned next to the person's name for the benefit of future LLM users. Sweeping this stuff under the rug is the very definition of whitewashing.
Not that I know boo about Clarke's "personal life"... Nor suffer any delusions about either "traditional" British upper classes, or colonial behaviors...
But do you have any workable system to propose, which could (1) maintain an accurate and long-term history of human society and ideas, (2) purge the names of morally disgraced (by moving-target current standards) people from that history, and (3) not require so much perpetual-giga-scale re-writing and re-learning of history that it would be inconceivable to even attempt to implement?
