Yeah? Name me one that was destroyed that hadn't fallen into some kind of gross sin...idolatry, homosexuality, bestiality, total disregard for human life....
God is merciful and very slow to anger, but there is an outer limit on His patience.
i will leave aside "gross sin", "bestiality", and "total disregard for human life" since they were not a part of your original claim, to which i was responding.
to cite only the most obvious and recent example: the nazi regime in germany, which was destroyed, not only failed to accept homosexuals, but actively and vehemently persecuted them.
perhaps you will claim it was not God who destroyed the nazi's but the devil, to punish them for failing to support his evil gay agenda.
Well, without an encyclopedic knowledge of all of world history the likes of which no one here could claim to possess, it seems to me that your original assertion - that all of the world's great empires have been destroyed as a result of tolerating homosexuality - has been modified in this latest incarnation.
Not only was the original assertion ridiculous, it would be impossible to prove or disprove. Historians can't agree on the causes of war and downfall during this century, let alone throughout history.
Thinking logically though, it seems highly unlikely that the common thread running through the downfall of every great empire was their tolerance of homosexuality. Somehow, I just envision there were greater causes and concerns involved, such as overreaching military ambition, famine, economics, and war.
