Where exactly is the evidence of ‘her racism’? Didn’t you have a disagreement about an empirical question? To be fair I suppose C) and D) aren’t mutually exclusive (depending on your interpretation; the wording is unclear) so that’s a poorly formulated question.
Also, there is actually more evidence of your racism than her’s. A main criticism you make of her citations is that they are from white researchers which is basic racial prejudice.
I thought your writing was good though.
