All parents are imperfect...
so are children(as children and as grown adults).
But let's not pretend all parents are good to their children. Some are down right abusive. Both my father and mother's rebellion against Jesus Christ had severe adverse effects on me. And my brother.
Parents involved in demonic activities are hardly worth defending. In fact, I'll be happy to affirm their judgment to eternal damnation next to Christ.
It is by the grace of God Christ stepped into my life. I certainly didn't get it from my parents. In fact-- I got the opposite.
Dad was a real prince too. He pumped a round in his head, but only after writing a manifesto railing against God-- how God "Couldn't keep his accounts straight." That is rich, railing against a god who you insist doesn't exist.
That is poison and is really no different than sacrificing your children to Molech. Santa Claus falls into the same category-- blinding children to the glorious gospel of Christ.
