She's certainly guilty of cultural appropriation. Since she considers herself 100% British, which is fine.
And belligerently doesn't what to acknowledge any other heritage in this particular interaction.
Doesn't know her ancestors specific African heritage, but then thinks it's OK to wear a mix of Traditional African attire. Now I think that's fine, the cultural appropriation narrative is BS, but given she's going down the extreme "I'm offended" narrative, surely using the same BS offence level, she shouldn't be wearing that if she only considers herself British?
On top of that she also changed her western name to an African name. People that consider themselves 100% British don't generally do this. So she's projecting an African image, but doesn't want to acknowledge it.
You would think she would be happy and proud to talk about her African heritage, particularly given the context of the event.
Runs a charity that's is specifically targeted to an ethnic minorities, and has potentially shown a racist attitude to a mixed race woman (now this is based on twitter posts from an alleged victim so could be complete BS).
Then we get to how upset he was, but video evidence show she wasn't and was happy interacting with everyone, not hiding in the corner as she suggested.
Basically this is just an attention grabbing grift.
