MarnetteD clearly has a watch list longer than my arm given his response time to reverting things, so he'll see what's been done and will just have to deal with it. While categories may require reliable sourcing, to a degree, the fact remains than for so many actors dating back to the 50s, 60s, 70s, especially, there is unlikely to be centralised sourcing, though many books are in print, such as actor biogs, few editors are really going to dig them all out and cite hundreds of actors entire career for each TV and film appearance, it would take months, even years, of effort. Wikipedia:Citing IMDb notes that IMDB has been a constant source of dispute over its reliability. However, for a category to simply state "this person was a Western (genre) TV actor" hardly requires AAA-rated reliable sourcing, and I do believe than IMDB meets the requirements as a tertiary source, confirming the fact that all those actors were active in that genre. Many of the individual articles for each Western TV series don't contain any more sourcing than IMDB, so it is not wrong to identify MarnetteD's reverts as "missing the point" when it comes to avoiding WP:POINTed behaviour. A tertiary source is better than no source at all, and categories are hardly top-level articles worth war-editing over. I find his behaviour protracted, bullyish and contrived as well as completely lacking WP:AGF standards. He needs to holster his attitude, because I'm not afraid to present his behaviour, including repeated history of the same behaviour, to ANI/EW and request that action be taken for his abuse of policy and anti-IP sniping motions. The lack of maturity exhibited in reverting those articles without consensus, openly taking advantage of my 48 hour block, will not be seen in good taste as it was clearly an opportunistic move, but a very stupid one which I don't take lightly. WP:BURO and WP:IAR applies here. We don't need strict reliable sourcing for a category as all those actors have an IMDB page, the majority of those IMDB pages are accurate, and if the category aims to improve wiki by indexing all the actors of that genre, it is for the better. To filter out those which lack a reliable source lacks NPOV because there are dozens of categories which make statements about things and people which don't have strong sourcing. But in this case, knowing an actor was a Western TV actor is hardly controversial. If MarnetteD reverts a single page he should be prepared to back it up with something other than WP:DEFINING, which is a guideline, not policy, but so far as "if the characteristic would not be appropriate to mention in the lead portion of an article, it is probably not defining" goes, there are considerably more articles that don't follow that ideal to the letter than do, which makes it a weak guideline to attempt to enforce unless an editor has a strong motive to do so. If he enjoys attention and drama, I expect to see him an ANI/EW before the week's out. 82.8.252.13
