I think you have put it very well,Pat. I think criticism is ok, provided it is constructive criticism. Shooters want to know how to improve, or to glean others thoughts on what thay would have done with the photo.
But definitely not criticism for criticism sake.
We have all started out somewhere, and all had some pretty bad shots, understanding of that goes a long way to grasping where that other person is at and encouraging them to keep working at it. (my 2c worth)
Well put Pat
