quincy j is MCA-affiliated and he is trying to lash out against Mercedes for dissing his "fam". The one-sided nature of his comments (all strictly anti-Mercedes) is pretty telling, as is the comments about Mercedes' management. It's all very clear to me. Mercedes has aggressive management and Mercedes is 'aggressive' in the diaries, which most likely are read by MCA personnel, whether on personal or company time. A backlash was INEVITABLE. You fight hard, someone swings back and you take a punch.
Mercedes,
My advice is quite simple and something you likely already know: take the positive out of this situation. Evaluate everything this QuincyJ character is saying as the "opposite position" and seriously consider whether his points have any value or usefulness. Re-adjust accordingly. You can even learn from your enemies, underdig?
