I reject Christianity, as well as the other Abrahamic religions and other organized religious groups. To reject Christianity, one must reject the divinity of Jesus. That doesn’t mean he didn’t preach some good ideas.
Jesus has never been my issue. It’s the entity that you would likely consider his father (what I refer to as The Divine) that I have complaints with. My parents didn’t choose to afflict me with a genetic (but non-hereditary) affliction that has shaped my entire life. My father didn’t choose to get skin cancer and die on his 54th birthday.
What people have done to me and mine, I can deal with. What has been done to me/mine or allowed to happen by The Divine is what infuriates and enrages me.
