I like to give myself the term of an Apathetic because nothing else seems to fit me. It's not a real term, but to me it means that I really don't care to give one bit of thought to something as deep, vast, amazing as the universe and pretend that I or anyone else knows what it's all about.
My feeling is that humankind is not at the stage of development as yet to understand the meaning of this puzzle that, with the given information and our limited mental capacity, makes absolutely no sense - at least to me . It is a puzzle, nonetheless for which I'm grateful for being a part of. I find it arrogant to assume we know. I can't understand a quark or a quasar or even how my cell phone actually picks up signals. I feel the mandate is for humankind to "keep on keeping on" until we're at a place to solve the mystery. As we continue to improve in the area of understanding the brain and actually how to preserve consciousness like that old Star Trek episode where's Spock's mind is in that big round globe while his body is no longer function, we will HAVE to redefine our beliefs.
I do like the term secular humanist. That term might need clarification. I feel I'm definitely that and that is the closest to my viewpoints.
In relation to terms that need clarification, I didn't know what a pantheist is until someone called me that. I had once been interested in the teachings of Alan Watts and read only one sentence in "The Book", but that sentence caused me to wonder. As I remember Watts was talking about it all being God - the planets, the stars, ourselves - all a manifestation. I'm not sure of that meaning, so it might be an interesting one.
The important part to emphasize, I think, is that most "non-believers", "non-religious" people have come to their beliefs from a life-time of searching - that they have been devout and many deeply religious at one point in their lives. They didn't "lose" their faith. They've evolved their belief system based on information that rings true to them. They don't need saving. What non-believers most need is a place where they can express their views openly and without judgment as do people of every persuasion. We're all travelers, stumbling around. We need to hold each other's hands and just keep on keeping on.
