not very much, that is to say I'm skeptical of metaphysics altogether. I'm partial to Wittgenstein's attitude, that is to say I think projects like pantheism deflate if you scrutinize them and inquire to what degree they say anything meaningful or well-defined about the world, or if they're really expressions of psychology or linguistics or desire.
I do agree with you that all kinds of belief systems may fulfill legitimate needs, but I think they're just that, personal, subjective and private expressions of the individual's attitude towards the world, not meaningful claims about the world as such.
One reason people opt for it, which I find understandable, is owing to the popular connotations that atheism carries, not unlike theism. You can avoid having to explain "I'm not saying I know that God doesn't exist". But the qualifier is explicit. One needn't necessarily be certain whether they believe in a God or not and I don't think that's well represented by the term "atheist". By the same token I don't think Deism is anywhere near atheism-lite. It is explicit belief in a God with the caveat that it's irreligious.
I like the term "apatheism" because it also captures the way I feel about the question of whether God exists.
I agree that pantheism is a misapplied psychological need, but no more so than any relgion or beleif system.
I've decided that to fill this need, it is useful to choose a fundamental belief system of some sort. I have choosen Taoism and parts of other Philosophical systems, like Stoicism, where I feel there are gaps.
