Well my theory is it wasn`t that he was really letting his true feelings be known, but rather he was trying to destroy himself. He was in an incredible destrucive mood like most alcoholics get into (your talking to the expert).
Remember, his first words when pulled over was "My life is f***ed". I`ve been there before quite a few times, and when you are in that state, self destruction comes VERY easily.
I mean what is the WORST possible thing he could have said to destroy his career? Well, he went and said it. To me though, right now that is the least of his problems.
It was obvious to me when the Passion was being released, the guy was under incredile pressure and he buckled. Before he started filming it and compared to when he finished, it looked like he aged 20 years. Let`s not forget all those liberal slimebags, anti-Christian zealots who did everything they could to destroy him, emabarrass him. They pretty much succeeded, yet these same slimebags will say nary a word on Islam.
