Look, I'm only stating my opinion and why I hold that opinion. Your answers have been very informative.
I just happen to see a difference between what Bush says and what other Christians say. When I listen to other Christians (including most of the ones on the Forum), I sense humbleness and awe when they talk about serving God. They don't claim or imply that they're more special than anyone else. They attribute their work to God's blessing. To me, it doesn't sound like they're trying to exalt themselves, but instead they're exalting God. They know that there is something greater than themselves. I don't sense any of that when I read and listen to Bush. He seems more like he's on a crusade. Again, that's just what I believe, and you can take my explanation for what it's worth.
