That seems like quite a simple, easy-to-understand point, but he doesn't grasp it - or perhaps doesn't want to grasp it.
OJ reminds me of a young child who doesn't want it to be bed time, so he decides to believe that it isn't bed time. There you go, mum - fixed that bit of reality for you, to my own advantage.
Maybe this sort of behaviour literally happened in his childhood.
I imagine his mother frequently sometimes gave into his nonsense, hence his adult ingrained behaviour. I suspect he learned at a young age that dishonest beliefs bring visceral pleasure, and hey, you get to despise your mum (and women) for being weak at the same time too. Win win.
