If I were a Christian I would also try to avoid discussing this aspect of Christianity, which is the point that Cofty is making here.
"But that was the Old Testament" is proffered over and over again out there in the real world. No, it's not said by professional Christian apologists (for the most part), but it is said over and over again my millions of nominal Christians. I've been hearing it for 40 years.
The point here is the separation of the Son from the Father and Yahweh in the minds of many Christians, not just the atrocities committed by Yahweh.
