In fact the proliferation of such sins in a society is itself God's judgment because they are socially destructive in themselves.
So, if a society (I don't know, let's say Sodom) is one in which homosexuality is prevalent, then the presence of homosexuality itself is God's judgment ?
Leaving to one side the extraordinary nature of the claim itself, you seem to be saying that God passed judgment on Sodom by ensuring the prevalence of such "sins", and then went and wiped them out for committing the sins.
A little harsh of Him.
Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
