Helix, I have a long list of jokes involving priests, nuns, non-Catholics, and etc. that are funny and most came from members of the denomination that is the butt of the joke. One that I find particular funny and was shared on this forum by an Episcopalian is:
Why are Episcopalian's poor chess players?
They turn their queens into bishops.
However, to joke about the deaths of 150,000 men, women, and children is beyond contempt.
You are purposefully ignoring what I posted concerning God's judgment in the OT. Other than the flood all of God's judgements concerned the land of Israel and the Jews and He was impartial since He judged and disciplined His own as much or more as He judged other groups.
Noah was the ninth generation after Adam so the population of the earth was comparatively small. The fact is we don't know the total population that was judged by the flood.
