If anything, my beliefs have gone even further into the atheist realm. I accept prayers from anyone but don't think they do anything for ME.
If anything my faith in humanity has increased; the selfless doctors, the strangers that send you a "Fuck Cancer" meme totally against their nature, the people I've known for a long time but have never met that message me routinely just to say hi, the NURSES... there is no better nurse in the world (except maybe the NICU) than an oncology nurse.
I know a lot of people who went the other way and have become much more religious. I can't see life that way. The same people who throw up the Hallelujahs every time some cross shape appeared at the scene of some tragedy but never seem to notice their god is who supposedly let the tragedy happen. Oh yes, I killed 6 people so you could see a cross shape and praise me.
I believe people are responsible for their actions, good or bad. Religion is a delusional way to avoid that responsibility.
Hope this made sense... I'm on "nausea medication" right now.
