Sigh. Be sure to apply your religiously-based condemnation and forgiveness selectively.
By the way, the story he’s talking about is the story of King David and Bathsheba. David wanted Bathsheba, so he drafted Bathsheba’s husband into the army, put him on the front line, had the troops abandon him, which resulted in his death. David then married and had a child with Bathsheba. God killed the child to punish David for his sin (because killing children for the sins of their fathers is a good idea). This is why, in the US legal system, we often kill the children of murderers as punishment.
I also have to wonder how the pro-life crowd could interpret God as being pro-life if He kills children.
