I think this depends entirely on the reason you take photographs, as you suggest
- If your purpose is to objectively describe the world for the benefit of other people - photojournalism - then editing is definitely wrong.
- If you aim to produce attractive and interesting works of art, then go ahead. Edit everything!
- If you want to become an excellent photographer, I suggest avoiding editing, because it forces you to get the best out of your camera, lighting & scene. Post-processing may improve a good photo, but very rarely fixes a bad one. That goes for some of the fancier features in most modern digital cameras too.
