Welcome to our forum.
I don't often find a "fellow atheist" so welcome indeed.
I perceive myself as a complex structure of molecules, sentient via my brain which is itself a complex structure of molecules. As such, it is doubtful that I have "true freewill," but I indulge in unconventional thinking regardless.
It sounds like you and Oni have quite a favorable and understanding relationship, so I am happy for you. I hope Polyamory.com will be an enhancement to your path in life.
Would you call yourself 100% atheist or partly agnostic? I'm just curious.
Glad you could join us in any case.
