The title of the thread indicates that the OP wants to compare the 7D to the 5D Mark II "or similar"...and yet you come into this thread trying to use the defense that the 7D ought NOT be compared to a full-frame camera. There you go, re-defining (invalidating would be a better word) the OP's question, and establishing ground rules for the OP.
Why not compare the 7D to the "similar". Why not compare it to a Nikon D3s...that body is full-frame...designed for fast firing and fast focusing...designed to be a good "action" camera. That would, or could, be the "similar" the OP asked about.
Putting a spin on your why all this hate for the 7D", how about, "why all this heated defense of the 7D" and "why all this telling people EXACTLY HOW it ought to be evaluated?"
It's okay for you to boast that the 7D "beats" a Nikon crop-body in some website's test, but it is not okay for the OP's question to be answered? It is NOT okay for the 7D to be compared against a full-frame Canon, as the OP's post inquired about? Again, "why all this defense for the 7D"?
The OP asked a question, and a Canon shooter opined that the 5D-II blows it away in terms of detail resolved...not surprising really.
