Deletion
The justification for deletion is an exercise in sophistry that by making information harder to access rather than easier defeats the entire purpose of a reference site. Categories are there to organise pages into logical groups; not only is categorising the meta-origins of characters entirely valid, tagging character pages is the only way to do it and thus a valid invocation of the possibility of exception noted in the [T:Tree] page.
Character pages I should note that already contain out-of-universe material in the form of the behind-the-scenes section. ;→ Koschei: : Life. But not as we know it. 18:10, March 29, 2015 (UTC)
I think this category should be deleted. Yes, some character pages contain behind the scenes sections. But when it comes to categories, in-universe articles should be kept separate from out-of-unviverse articles. Except in special cases like "Doctor Who actors that exist in the DWU".
