There's your problem.
My eldest brother is a college chemistry professor, extremely smart, and a Unitarian. I don't get it. How can you believe in a religion where 2+2=5, or maybe 3.4, or possibly an attractive shade of blue, or "whatever you think it is" and integrate that with being a scientific person?
Unitarianism gives complete control of the Almighty to the individual. That's why people like it. They can create their own god.
