You are really trying to justify tossing up one's own children as offerings to an angry mob, seriously? I think most decent parents would offer themselves up before sacrificing their children.
First Point. They were not children. In fact they drugged their own father after leaving Sodom, so they could have their own children.
Second Point. Lot should have left when they were children, not wait around town for destruction to force him to leave.
Third point. God did the destruction, not man. If man takes matter into their own hands, then they are evil themselves.
This was a true story, not some made up fable to incite modern day believers to incite mob violence over a action that offends them.
It is a warning that when God leaves town, there is no turning back. People are free-moral agents, and they can choose their own path, but if one is offended at history, it should not be because it actually happened, but because no one learned anything from what actually happened.
That is the problem with picking and choosing parts of the Bible. If it is not taken as a whole, it is not very trustworthy. There is a lot in the Bible that is hard to explain, but when one refuses to accept what one
does understand, is where judgment comes. If any one starts spouting off the Bible for his own gain, or to the offense of others just for the fun of it, then they are wicked. If God himself causes things to happen that are unexplainable and offensive, then no man can take credit for it. If he does, then that person will be just as cursed as Lot was. No one person is holier than another, and most judgment starts with believers first and then those who choose to ignore the facts.
