KE INTO ACCOUNT THE BODYS HIGH DEMAND FOR PROTEIN, TAKE INTO ACCOUNT HOW THE BODY DEALS WITH HUGE SURGES IN AMINO ACIDS (EXAMPLE= WHEY) , TAKE INTO ACCOUNT THE HUGE THERMIC EFFECT OF DIGESTING PROTEIN, TAKE INTO ACCOUNT THE SLOW RATE OF DIGESTION MEAT HAS, TAKE INTO ACCOUNT THE TURNOVER RATIO OF PROTEIN INTO GLUCOSE, AND TAKE INTO ACCOUNT THE RATE AT WHICH THAT TURNOVER OF AMINO ACIDS INTO GLUCOSE OCCURS
AND AGAIN, I ASK YOU, EXPLAIN TO ME HOW PROTEIN IS GOING TO MAKE YOU FAT
^^^^^
the above is the argument
protein wont make you fat
as for the theoritical ability for ingested amino acids to go through the processes leading to some fat storage, THAT WAS NOT THE ARGUMENT
but, i will argue that that process is purely hypothetical. and gluconeogensis is depndant on lack of glucose not presence of amino acids
howver i could be wrong and im waiting for some kind of study from the EXPERTS 
All calorie is, is a measure of heat. It is the amount of energy required to raise 1g of water 1 degree celcius. The "calories" we measure are Calories or Kilo-calories.
Excess ingested calories are extra energy. Ingest an amount of energy above and beyond what your body exerts during that time period, and the excess energy has to be stored.
It can be stored through synthesis of new proteins, glycogen, or fat.
I don't think people realize how little of the protein we ingest is converted to muscle mass. VERY, VERY few grams per day at best.
If you can convert 20g of ingested protein to new muscle each day, you can expect to add over 320 pounds of pure muscle mass by the time you're 38 years old. If you're 180lbs now, you would be 500lbs of shredded beef at age 38.
500lbs of muscle mass at age 38 from ONLY 20g of protein synthesis a day. If you're eating 600g of protein a day, what do you think the extra 580g are going to? (assuming you're adding pure muscle mass at the astronomical rate of 20g per day)
There are benefits to high protein diets, which Dante has listed here.
Protein has a high thermogenic nature. The digestion and utilization of protein burns up a decent amount of its total caloric content.
To be stored as fat, protein has to undergo a few biochemical processes which also cost energy.
The total process of human digestion involves many processes. While it would be wonderful if it were much more simple, it isn't.
There are ways to increase caloric intake without increasing fat storage.
One method is to alter macronutrient levels by the day. If you increase your intake of protein and specific fatty acids on days that you decrease carbohydrate intake, you can take advantage of the thermogenic nature of protein digestion as well as the thermogenic benefits of certain fatty acids (gamma linolenic acid is one I've written about)
The resulting glycogen depletion allows for a period of higher carbohydrate intake where excess energy (in the form of blood glucose) can be stored as muscle glycogen instead of being stored as fat.
Once the body exhausts its ability to store glycogen, fat storage will return.
This is the basic concept behind our carb cycling approach at Troponin Nutrition.
There is absolutely no need to produce a study. Any physiology, biochem, exercise physiology, biology, or nutrition text book will explain this process in the metabolism section(s).
