Part of the problem is that the term HDR is applied to more than one technique..
You can do it with three or more (and usually seven or more) RAW exposures, combined with HDR software and tone-mapped, then exported to a better editting package to be finished. Done right it will be instantly recognisable that something has been done to someone that understands exposure, but to a person off the street it might just look like a very good photo. Call this HDR.
Others will include taking a single raw exposure, adjusting the exposure in post to get three pseudo-bracketed images, then combining and tone-mapping and editting as above. It won't capture the same dynamic range, but done well it can look realistic. Call this pseudo-HDR.
But the term is also applied to taking a single exposure and running it through tone-mapping software to get the "HDR look". Call this tone-mapping or the "HDR look".
What gets people wound up is that HDR does not have to have the HDR-look, and the HDR-look does not capture a high dynamic range. So when you do "HDR" with an image you will always get judged by people's ideas about what is and isn't HDR.
The above are only my opnions.. and I have those about art in galleries as well..

.. and the great thing about opinions (as a good friend used to tell me) is that opinions are like a******es, everyone has one
