Oh wait, so Photoshop is FAKE, and not art ? Thats the same reason why editing in video/film is so underrated. There are so many great movie with crappy shooting saved by post ( Easy Rider, for example ), and there are many well shot movie turned into crap by post.
Or what about cooking ? By your definition, it should not be an art form, because the only art is in the process of making bread or sauce. Cooking just simply put those RAW material together, and "edit" them , so it should not be an art.
Shooting from LCD or VF does not matter, as long as you are comfortable enough to get the shot you want. I sometimes run a production for wedding video, and guess what, that one dude who often use Auto Mode ( Focus and Iris), which is labeled "amateur" by the "pro", has the most useable shots. He knows how to use technology to compliment his manual skill and not totally rely on one.
Shooting raw or photoshoping are both art, in their own unique way. They compliment each other to produce the final art work. Therefor, praising one "art" but bashing the other "fake" is just simply ignorant.
As the poster above said, you will rarely see a rubbish image saved by post. But when it does, its gold, because more often than not, reshooting is not an option.
The only constant in this world is change. Live, learn, and adapt. It will make you a better artist when you step out of your comfort zone to accept new challenges and use them to your advantage. Dont be scared, photoshop is just a software, it wont hurt.
