We don't need a profile for Fierce (and his other 4 other suspected handles).
This is who Fierce is:
Since he is on this board 7 days a week; morning, noon and night; the kid doesn't go to school, doesn't have a job, and doesn't have a wife or family. He lives at home with his mom. His social immaturity and oppositional behavior would suggest that he doesn't have a girl friend nor friends.
He is betwen 18-20. Graduated from high school and maybe taking online classes from some community college. He was unpopular in school, due to his abrasive yet arrogant personality and so developed a thick skin to criticism and redicule. His personality is defined by his internet personna, spending 6+ hours online per day.
Its most important for him to be "right" because he gets so little positive attention.
And when things get too hot for him, his defense mechanism is to change the subject matter, typically by introducing Rondo into the thread.
