Why was the destruction of Sodom and Gomorrah not an act of God's wrath?

Les explains that the destruction of Sodom and Gomorrah was not the wrath of God per se; rather, it was a disciplinary action. He notes that God did not really make them suffer like they will in the tribulation. Instead, it was an instantaneous wiping out of Sodom and Gomorrah, and it was plowed under. The cities were turned into ashes, condemned with an overthrow, making them an example. Les points out that an example is an example and it is to tell us something: the reason God destroyed Sodom and Gomorrah was the homosexual lifestyle, and the world is never to forget it. It is to be an example unto those that should hereafter live ungodly. Les also mentions that archaeologists have not really proven they found Sodom and Gomorrah yet; some are convinced it is under the Dead Sea, but they have not been able to excavate it.
