Well Petersen is definitely Alpha male by some general standards, considering everything he has achieved, his personal career & projects, his fame and money etc. You can do a lot worse than him.
That's why I was at first inclined to type him LIE. However, I could also see the arguments for Se-polr / LII and in that case he indeed could call himself an Alpha male of some sorts. anyways he's too .. far.. removed..from ..reality.
