A useful distinction could be made between a photographer and a camera user.
Anyone who, at least in theory, does not understand aperture let alone how to use it well is not a photographer just a camera user.
Most point and shot folks are camera users not photographers for instance. In fact for most point and shoot users get one precisely because they don't want to be "photographers".
I was at a funeral service recently. The elderly lady in front of me took out her PS. Hit the on button, Framed the shot in LCD, hit the shutter release, hit the off button - done.
She was a camera user not a photographer.
