A sort of George Clooney, I'd guess (no, I'm not implying he is an INFJ). He'd probably not be very dominant though.
A man builds. A parasite asks 'Where is my share?'
A man creates. A parasite says, 'What will the neighbors think?'
A man invents. A parasite says, 'Watch out, or you might tread on the toes of God... '
I have only known one 'confirmed' INFJ male in my lifetime... and he was not what I believe most people would consider an Alpha male. He did possess some of the characteristics described above though. Like he could kinda *switch/snap* and become very critical, judgmental of others, arrogant <--- but those aren't Alpha characteristics. They are more like 'I'm suddenly pissed that I'm NOT an Alpha' characteristics.
