` :::::But, Kwami, our disagreement has never been about speech communities, but about data.  There was never any attempt to say that ``there are 5 Khoisan languages in South Africa`` or anything like that.  It was strictly about data and the existence of a particular class of sound in a particular group of languages.  It was never about whether there were speakers of those languages or notthat's the totally irrelevant spin you put on it.  In the data for five different languages there exist bilabial clicks.  Whether there are extant speech communities is irrelevant.    `
