> There's nothing comparable to that at all in the New Testament.

There certainly is. In fact, at one point, Jesus even brings up Sodom as an example!

See Matthew 23, where Jesus calls the scribes and Pharisees "children of hell" and says that all the righteous blood shed since Abel will be required of them, prophesying the Siege of Jerusalem and the destruction of the temple ("not one stone will be left upon another.") Or the famous incident where he drives people out of the temple with a whip. Or when he says hate is the same sin as murder and lust the same as adultery, and those who commit them will end up in hellfire (in the Sermon on the Mount, no less.)

Or the reason he so enraged the Jewish authorities, he repeated claims that they were going to lose the kingdom. For example, after he healed the centurion's servant: "When Jesus heard it, he marvelled, and said to them that followed, Verily I say unto you, I have not found so great faith, no, not in Israel. And I say unto you, That many shall come from the east and west, and shall sit down with Abraham, and Isaac, and Jacob, in the kingdom of heaven. But the children of the kingdom shall be cast out into outer darkness: there shall be weeping and gnashing of teeth."

Or when he says the Capernaum is going to have a worse time than Sodom: " And thou, Capernaum, which art exalted unto heaven, shalt be brought down to hell: for if the mighty works, which have been done in thee, had been done in Sodom, it would have remained until this day. But I say unto you, That it shall be more tolerable for the land of Sodom in the day of judgment, than for thee."

Or his comments on people that don't forgive: "And his lord was wroth, and delivered him to the tormentors, till he should pay all that was due unto him. So likewise shall my heavenly Father do also unto you, if ye from your hearts forgive not every one his brother their trespasses."

Or the Parable of the Vineyard.

Or this particular memorable castigation from John: "Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it."

This is a view in the popular imagination, but it isn't really supportable after reading the gospels.

I don't agree at all, and your examples actually prove my point.

Yahweh was literally flattening cities, killing Egyptians with plague, destroying Cannanties by force, requiring his followers to sacrifice their children (!).

None of the 'hard advice' given by Jesus in the examples are remotely equivalent to this, nor do they paint a picture of an angry or despotic figure at all.

Jesus is laying Moral Judgment. That's not the same thing we see in the Old Testament.

I guess I fail to see the difference between God destroying Sodom in the Old Testament for their wickedness, telling Abraham he would spare the city if he could find even ten righteous men in it, and then Jesus claiming to be God in the New Testament (John 8) and saying that soon, Capernaum will be judged and face a fate even worse than Sodom because Sodom was morally better than Capernaum.
