@Nermie01 "You can say "this feels more like a shounen than seinen" all you want, it doesn't matter because the story is released in a seinen magazine. These are facts, there is no arguing them."
There is though, and that's what we're doing right now.
Just because its targeted at seinen readers doesn't mean the protag has to be male or even a seinen(middle aged man). Heck, a lot of seinen manga are themed at appealing to fathers who are part of that demographic so sometimes there are those 'cute' stories with children, adult women (regularly in action genre manga) and school girls (though some of it is also just pedo).
You're basically admitting I'm right with this: "Sure, the magazine will decide what to include in their releases based on the general desires and interest of their target audience, and that influences the content." Then denying it to seemingly save face.
Demographic is target audience and the target audience has preferences. Demographic is just a convenient label for readers to know: "Here are some manga with content we think your demographic would like". Hence content is always relevant to the demographic label, hence nothing was wrong with my initial comment.
To make it easier to attain and enjoy manga of similar content, they are published in the same magazine, catering to the same demographic. However, you along with many others seem to think the process somehow goes backwards.
There are many works published through means other than magazines that carry the same demographic labels because being in a magazine isn't the be all and end all of the criteria for said labels.
