Fiend God
The cheese is being marketed in Australia, so I don’t think Americans are going to be too worried, whatever their skin colour.
The term is certainly known as a racial epithet in the UK (see the video I linked earlier), though I’ve not heard it used for many years (outside re-broadcasts of old material). Whether it is known in Oz is surely the crucial point, though it could be a generational thing; I’m pretty sure Till Death Us Do Part would have been shown there. The fact that a name change has been proposed suggests that at least some people know about it.
In the current global market of ideas it's also easy for someone in one country to claim to be offended at something in another country.
