“Resentment” is the correct term. He knows, or at one point knew, deep down what real success, charm and being truly admired looks like, and he’s never gotten it. We can argue until the cows come home whether Obama deserves his accolades, but the fact remains that the admiration he gets is real, and that people really do like him. He has a real wife and family, not just one paid to show up.
Donnie knows deep-down that nobody actually likes him. They like celebrity. The glitz. So when a black man gets everything Donnie himself craves and knows he can’t ever have, it all must be destroyed. He’s a sociopathic, oversized toddler throwing a temper tantrum. So, if it sounds like I feel sorry for him, I don’t. He could have grown up at any time. He chose not to.
