I picked "No intervention against tyrants". Only a few people chose that which surprises me. It's not really my primary reason, which is closer to lack of evidence, but it's worth discussing.
Let's just take the Jews, from the Bible and later history. Supposedly they were God's "chosen people" and for a while it seemed that one of the worst things another tribe could do was to threaten or hurt them. God visited a series of plagues on the Egyptians when they wouldn't "let my people go", then parted the waters for them to escape. Then he helped them to conquer Palestine (or whatever it was called then).
Then things started to go pear shaped for the unfortunate Jews. They got kicked out of their country and their temple destroyed by the Romans. No intervention from God. Then they were persecuted in just about every country they lived in. Still no intervention. And finally, the Nazis tried to exterminate all of them, and killed 6 million. Where was God? Absent, it seems.
