Ignorance and illiteracy are not hand in hand. Ignorance can come from simply not being present regardless of education or literacy.
I took what you said earlier
clearly as meaning in some periods of time the WCT Finals and masters were more valued than the AO. If that is the case then it also goes also that AO's achieved in that period should be valued less than when it has been regarded as equal to other slams. Anyone who has those particular AOs included in their career achievements should have the fact noted. Not doing so would be deliberate perpetuation of ignorance.
The question remains is: when was this period? Is it a clear-cut, finite period or does it have grey edges to it? If 1985 is the cut-off year, why? When did it become a top tier slam again?
Not being argumentative as I totally see your point about eras etc putting varying importance on different events. But the brush should be applied when it suits and when it doesn't equally.
On the light-hearted side.... It is a small irony that you spelt illiterate incorrectly.
