My sister is a fundamentalist Christian and she explained to me that God made people different by design.
In particular, she mentioned gays and drug addicts. Not in the way that both are bad and need to be stamped out.
She said that the majority of folks are heterosexual. Some are gay. We are not capable of reaching into the psyche of either and re-wiring their instincts. That's just the way they are. They are all God's children and so we are compelled, by God, to love them all as we would ourselves.
She and I are not more holy or less so than Gays due to our heterosexuality.
The same is true in her mind for drug addicts, alcoholics, and all others who carry different burdens. We cannot judge their actions by our standards if we are not carrying their burdens. We can help when called upon or we can turn away.
She feels that those who are compelled to the abuse of drugs or other life altering behaviors are compelled as are those who are prone to allergies or clumsy. That's how God made them.
I am not of the mind that a man is either of science or of religion. At his best and his worst, man exists in the misty glimmering where the falling angel meets the rising ape. That he chooses a direction from that point defines him as human.
The GOP is slowly wise-ing up and coming to the realization that the social conservative agenda of the radical right-wing is what has in large part brought down the party.
