A slime-ball is easy and obvious to recognize. A narcissist, on the other hand, is actually subversive, deceptive and operates in the shadows without a conscious - and much more destructive. I don't know Deion obviously - but I hope he is neither.
From another respected poster here: "I know the man personally and he’s not the slime ball y’all make him out to be #OnHere. Is he a narcissist? 100%. Is he self serving? 10000000000%."
