i do not know the behind the inclusion of johnson's racist quotations, but they have been removed. they are not his best quotes and are out of place on here.
I think you have to accept that Johnson's "racist quotes" were a product of his time. To delete them is to attempt to rewrite history and to make out that Johnson was a different man than the one he was.
Good and original
Regarding the misattributed quote "Your manuscript is both good and original, but the part that is good is not original and the part that is original is not good": Something similar was used by politician Arthur Balfour, but with "trite" and "true" in place of the adjectives found here.
