I'll have to say..
His premise "freedom from religion" is somewhat a strong belief that he holds in which death is a choice he will make instead of choosing another way of life. Can his "freedom from religion" be a religion itself?
So let me get this straight. So at first you doubted the tenants of Christianity and decided that they were not sensible and truthful. Did you then doubt the God belief right away or did you study other beliefs before you reached your conclusion.
True. A bias can be instilled within the context of living you originated from. If your family are Christians for example, a person has a more tendency to become a Christian and so forth.
Ironically, I am a a biology researcher.
In regards to the evidence, I want it based on the scientific method.
The scientific method: "based on a collection of data through observation and experimentation"
Can you give me an observable evidence of a change of kinds. Something that I don't have to receive by faith.
