Styles, as to why I can't help, sorry.
All I can suggest is put your ear plugs in, hard hat and body armour on, call and politely ask, carefully explaining that you have read her profile carefully, you are an American, visiting the UK but that you are a person of colour and would she consider relaxing her exclusion rule.
All she can do is say no, scream down the phone, hang up or just possibly say yes.
