Ezekiel 5:10

I don't see the connection. That passage isn't advocating cannibalism, it is portraying it as a divine punishment.

It's portraying it as a consequence - he was too. If there is no food, he will have to feed his kids somehow, etc.

"I will be forced to eat my neighbour" versus "Sky fairy warns that people will eat one another"

The second is more ridiculous, and more people believe it.
