Welcome to Less Wrong! You seem to know your way around pretty well already! Thanks for introducing yourself.

Also, I really appreciate this:

I alternatively describe myself as a naturalistic pantheist, since the Wikipedia article on it nails my self-perception on the head, not to mention it's less confrontational ...

The article says that of naturalistic pantheism:

Naturalistic pantheism (also known as Scientific Pantheism) is a naturalistic form of pantheism that encompasses feelings of reverence and belonging towards Nature and the wider Universe, concern for the rights of humans and all living beings, care for Nature, and celebration of life. It is realist and respects reason and the scientific method. It is based on philosophical naturalism and as such it is without belief in supernatural realms, afterlives, beings or forces

Wow, I had no idea you could believe all that and still count as a kind of theism! Best. Marketing. Ever.
