I agree with you completely.

You give the reference to Fanny Austen’s 1809 diary and An African Story in the notes at p332 of  Claire Tomalin .Jane Austen.  A Life. 

Claire Tomalin gives the full text of the story at Appendix II beginning p291.  Tomalin describes the story as “wholly sympathetic if also thoroughly naïve” (the hero sets off from his African village to hunt a tiger in preparation for his wedding to his beloved) and adds the information that one of Mrs Austen’s cousins, Mrs Samuel Cooke also suggests disapproval of slavery in her novel Battleridge.

In Persuasion the comments made about the intelligent and hardworking Nurse Rooke add to my belief that Jane Austen was well aware of conditions outside her own circle.

Footnote 11 lists, as co-author of "The Post-Colonial Jane Austen," a certain "You-me Park." The name would read right-to-left in Korean, which would yield "Me-You." Possibly her parents were admirers of�Buber's "I-Thou" and at naming-day did not forget. Think of the early Puritans, endowed with such names as Prudence, and Patience, and Do-Good.

A white white defending a white... though slavery was abolished it was still in practice.. as said said, its silly to look at it as an abolitionist stand

I'm doing a research titled: Was jane Austen Black?

There is so much color in her books, how did we miss that?

 When  Edward spoke  to ordinary  audiences he   did not  fall into the post-modern  trap--he  was  a fine   man a  patriot  and he  gave Palestine a face--but he is  just  foolish about Jane Austen or being  deliberately provocative.  We know  from Austen's letters  that she "loved"  Clartkson.  The  article is  as is post modernism  intellectually   dishonest  BUT IThis  article is too hard  on Edward   who loved Glenn Gould and Bach --and I  suspect  Jane  Austen. The  Sokal  Hoax   explains  Edward's misreading  and I wish the  author  had said more  about it. The humanities  last time I  looked  were in the  grip of it.
