So this Sunday I’m going to try the UUs. There is only one (I think) in my town and I’ve never heard that they close for the summer.
Just to clarify, I tend to think of Universal Laws and physics as God.
And I’m pretty sure what my objectives are in my pursuit, just what I stated, and I’m comfortable with them.
In addition to UUs you might try Quakers. No hymn singing. No creeds. Just silent worship/meditation, with anyone who feels moved standing to speak.
The “Quaker witnesses” include Community, Equality, Simplicity, Peace, Integrity. There are different flavors of Quakerism, from what you described you will want to stay away from Evangelical Friends. Try to find an “unprogrammed Meeting”.
This is a great site that hasn’t been mentioned yet: selectsmart.com. Take the quiz and it will give you an answer as to what’s closest to your belief system.
Here were my results:
I too got 100% on Secular Humanist. Unfortunately I would tend to disagree with many of the SH’s tenets. It seems to me that SH’s hold being human to be the ultimate level of existance. That humans are perfect and all our flaws only highlight that perfection. I tend to disagree with that, which is why I found Transhumanism a much better substitute. Transhumanism is secular humanism, except that the belief that through our actions and technology (just an extention of ourselves really), we can better all of humanity, and rise above our flaws. No divine interaction necessary- though still possible. 
Got 100% Neo-Paganism.
I see I’m following the right spiritual path.

(I got 42% Scientology :eek: )
I’ve never seen a secular humanist claim ‘being human’ was perfection in and of itself. From the Council For Secular Humanist website.
What Is Secular Humanism?
Secular Humanism is a term which has come into use in the last thirty years to describe a world view with the following elements and principles:
* A conviction that dogmas, ideologies and traditions, whether religious, political or social, must be weighed and tested by each individual and not simply accepted on faith.
* Commitment to the use of critical reason, factual evidence, and scientific methods of inquiry, rather than faith and mysticism,** in seeking solutions to human problems and answers to important human questions.**
* A primary concern with **fulfillment, growth, and creativity for both the individual and humankind in general.**
* A constant search for objective truth, with the understanding that new knowledge and experience constantly alter **our imperfect perception of it.**
* **A concern for this life and a commitment to making it meaningful through better understanding of ourselves, our history, our intellectual and artistic achievements, and the outlooks of those who differ from us.**
*** A search for viable individual, social and political principles of ethical conduct, judging them on their ability to enhance human well-being and individual responsibility.**
*** A conviction that with reason, an open marketplace of ideas, good will, and tolerance, progress can be made in building a better world for ourselves and our children.**
Everything I bolded seems to imply imperfection in humans and a desire to perfect it through study and work.
