I don't think that is the point. I think the press or authorities use a term to identify a group where there appears to be a particular problem. So when talking about operation Yew tree, the term celebrity appears all the time, not singer or dancer or actor or DJ.
It is the same as the problem the Catholic church have had with some priests, They don't use the term Christian, Presbytarian, or Methodist, They use the term Catholic, because that's the group which identifies them most closely
