And thus we have a classic correlation/causation problem.
To a certain extent I think those trying to "disprove" that religion had something to do with it are missing the point (and we all know how religious I am). At the end of the day spiritual belief makes Trout feel better, feel more connected to his fellow man, and appreciate his life to a greater extent and the things that happen to him, whether divinely guided or coincidental, a little bit more. He's gained a greater appreciation for the fragility of his life and the strands that connect him to those he loves.
If this was the only aspect of religion that mattered, would any of us have bad opinions of religion? I know I wouldn't. Hell, I'd probably be the Pope.
There is not one ounce of hatred of others, exclusion of "sinners," or moral justifications to commit petty acts or crimes against his fellow man contained in Trout's post. No one should have a problem with that kind of sincere belief. There's even a bit of acknowledgement that other beliefs might have access to the same kind of knowledge or power.
It doesn't matter whether or not it objectively happened, what matters is that it is unequivocally a positive in this instance. Here, religion is all upside. And frankly, it's a little twisted to try and take it away from him.
