"Stub" tags, like these examples here:

Military stubThis military article is a stub. You can help Wikipedia by expanding it.
This article related to a book about religion is a stub. You can help Wikipedia by expanding it.

...are a call out for editors to help Wikipedia by expanding the article.

They are not a request for you to pounce upon an article in need of more references and issue an AfD because, by golly, you're going to try and murder that poor puppy dead before somebody else comes along and helps Wikipedia by expanding it.

Just because you don't like books critical of Islam or purple-haired anime characters doesn't mean you should hover over the stub categories, like a shark cruising the reefs, looking for things to gank in the night.
