You're surely referring to my "depopulation" of Category:Southern artists: I mean, for every artist who was marked with this category, I removed the category.

The reason was simple. For every state of the US, I think, there exists "Category: [state] artists"; and certainly for every one of the artists whose articles I fiddled with, there was one or more of Category:Louisiana artists or whatever. For convenience's sake, let's stick with female artists from Louisiana. If somebody is so notably a Louisiana artist as to deserve to be so categorized, she's also automatically a Southern artist.

(I suppose I could imagine an artist who never stepped out of the Pacific northwest  or indeed the Netherlands or Karelia or wherever  but who yet was claimed to have a "Southern sensibility". But I saw no such claim made for anybody there.)

Thus Category:Southern artists seems utterly superfluous. 

I don't think there's much point in discussing any other contributor/editor's attribution of motives and predilections to me, so I shan't respond. (If you're that dissatisfied or otherwise concerned, there are channels by which you can complain about me to Wikipedia in general.) However, I'm happy to clarify anything that's not clear in what's written above, and I'm open to an argument for how I'm wrong and Category:Southern artists is not rendered superfluous by Category:Louisiana artists and the rest.
