Why do most Christians say Sodom & Gomorrah were destroyed because of homosexuality when...?

They were located on the southernmost point of the Dead Sea.

Towards the south-east end of the Dead Sea. There is geological evidence to support the suggestion that the south-east end of the Dead Sea was devastated by an earthquake between 2100 and 1900 BC, which could have unleashed showers of steaming tar. Bitumen is still to be found in the region.

The two cities were in a valley which now is submerged and archaeologists think their ruin was accomplished by a great earthquake, probably accompanied by explosions, lightning, ignition of natural gas, and general conflagration.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
