Norudeshitrequired - I see your point regarding street vs patois and it would be good for the OP to come back an clarify!
I must admit I made an assumption based on my age! I was in school/college/uni less than 10/7/5 years ago and I have younger brothers and sisters as well as cousins etc. I live in South London so in terms of 'black' culture im not sure there is anywhere else in the UK that has more.
IME Patois usage has not been prominent in youth dialect since the 90's. It certainly dosent cross over to white or even african children in the way it used to since 'street' slang has replaced it AND as its own language is comprehansive.
I do see young west indian children/adults flick between patois and street slang but I do not and have not in a long long time seen anybody else do it. I would say that amongst black kids though, parts of the Nigerian and Ghanian language are becoming widely used and I wonder if this is reflective if the music but this is a kind of internal black thing and its something thats done amongst friends and 99% time done in a playful context.
Street slang is definately english and used amongst white, black, asian and what ever else in equal measures and I dont think anybody needs to move into patois to improve thier social standing. It just wouldnt and in fact never has worked!
You are right ignorance and racism whilst close are not the same, but for me neither are something I am prepared to expose my children to especially when it stereotypes them!
So for that reason I would not be happy with her use of this in public with children in ear shot (especially black children). We all want to protect our children and if her child is schooled around here I myself would advise her to tell him to stop. It will do his credibility no good whatsoever.
Similalry though, I find it offensive in equal measures when white people think they should talk that way to me because I am black and therefore equal street. I binned a boyfriend for that shit.
Yeh and F* rappers! Well most of them ;-)
