That was...a lot to unpack.
Might I suggest breaking down your otherwise stream-of-consciousness argument into coherent paragraphs to make it a bit easier for us to digest your argument?
Also, clearly you are pissed about the choice of casting, but not one part of your rant suggests any casting alternatives.
Depending on who one could suggest, then the whole argument of colorism could come into play (She's too light-skinned, too dark, etc.).
Additionally, the initial postings about the film indicate the time period they are covering, from her enslavement and escape, to helping those attain freedom pre-Civil War, so roughly from her mid-lates 20s (27) to her late 30s (38-39), so you also now have an age range. - Erivo is 31 by the way.
This film is also being worked on and created by a team that is headed by POC (writer/director/producer), so this is being handled by the people who should rightfully be telling her story, and presumably aren't trying to do a half-assed whitewash of her life.
TBH, I'm glad you were able to get the lead out, but a little digging shows that your argument is all rage and no solutions based on assumptions for a film that doesn't even begin production until next month.
