No, it does mean you're wrong. Either way. You just have to think it through.
The Bible's infallibility is a false doctrine created by man.
The cultures that inhabited Canaan, and which were destroyed by the Israelites, were rife for destruction. They were profligate, murderous people who actively tried to subvert the religion God was attempting to establish. They passed infants through the fire, meaning they were burning them alive. To drown out the screams such cultures would beat loud drums, which also enhanced the cult's hold on the people. Also, one reason they had many children to sacrifice was because of their fertility rites, which were drunken orgies. That aspect of the religion was attractive to certain elements of the male Israelites. And when seduced by the surrounding peoples, the Lord knew he had to remove the cesspool to keep these elements out of it.
The infants who were taken were innocents, but murder is not something God can commit. His acts are judgments; we are subject to Him, and He certainly doesn't have to answer to Buddhists, atheists, theists or anyone else. In Enoch's case, He showed him the secret acts of the people to perish in the great flood, and Enoch went from misunderstanding to understanding in just that amount of time for him to see it. In other words, you have no idea what you're talking about and yet you feel educated enough...knowledgeable enough...to judge someone who knows everything, and who sees the hearts and acts of all men. Do you really feel qualified to do that?
