She does seem a little black*ish...
“including the fact that there’s no evidence to say Fishburne is Latino”
Sadly, many blacks create non-black ancestry in their minds - a sort of defense mechanism. Here in NJ, we have a small population of mulattoes along the border with upstate NY that claim to be an Indian tribe (the Ramapoughs) - yet there is no evidence at all that they have Indian heritage. NY and NJ humor them with recognition, while the federal government won’t. If you see them, they look like mulattoes and many have Dutch surnames (the original settlers of the area were Dutch) - but they maintain the charade because they don’t want to be identified with the larger black population in the US (many of which also have white blood).
