"We conclude that in the today's art world, journalism and documentary are bad words."
In the art world, photojournalism and documentary work are bad words simply because they are not understood in any way, shape, or form; especially photojournalism. You can explain till you are blue in the face, and fine artists will just never get it. They will critique a journalism photo the same way they will critique an art photo. They just can't get rid of the ego and view a photograph as anything other than a photograph. They do not understand that it is journalism with photography as the tool, rather than a photographer's artwork with journalism as the subject matter.
Screw 'em and keep taking pictures. Photojournalism and documentary work by purpose and by nature is to be published and distributed to the masses (and *quickly*), not be "sold" to a gallery so it can be framed and presented on a wall. If it somehow ends up there some day, whatever. But your primary purpose is the publication and distribution of information, not the creation of art.
Even more sickening than the fact that art photographers just don't get journalism is the slew of art photographers who call themselves journalists or documentarians, when they are really just making art using techniques or looks of documentary photography. The number of people I have heard describe themselves as journalism or documentary photographers is about 10 times the number who actually are.
