There was an earlier, better article in the Guardian by Lola Okolosie on this topic.
On balance I do think she is a bit racist; there is nothing to say that rap is the exclusive preserve of black people, but then again it is a very black form of music which originated in black communities and has strong cultural sensitivities which people need to be alert to.
What makes HoneyG so awful is firstly the fact that she is so talentless; secondly, and more disturbingly is the fact that she is a glitzed up, sanitised and packaged version of a rap artist who is simultaneously taking the piss out of rap. That makes it a bit racist, IMO. Every time people ring up and vote her in, they are voting to ridicule rap music. If she had a little talent, or didn't mock the way she thinks black people speak buy using dumb expressions like 'Norf Weezy' (nobody actually says that) or 'get my flow' perhaps it wouldn't be quite so appalling. But she does.
You cannot compare her to Eminem because he is a complex, successful artist who generates his own material, in a different league. HoneyG is only fake. I feel a bit sorry for her because she is clearly the joke candidate but has now got to see it through, as have the judges. In fact, yet another Guardian article has likened her to Trump - the outside, joke candidate whom nobody ever believed would go the distance...but hang on....
