Not making itself known would be a form of deception, especially when there are people who desperately wish to believe in such a thing. And considering we see no "fingerprint" of divinity in existence, the belief that there is no such thing is a rational position--again, the result of deception. Aren't you? After all, you seem to be arguing that choice is important to God; the very idea that God has a preference means he is a personal god. Would you say for the people who have seen "plenty of evidence," that they have no other choice as sane human beings but to believe? This is a logical fallacy. Why would someone need to believe in a concept to make claims about it? And we make irrational choices all the time, as well. Sure they could. One could easily believe that the "unmistakable" public appearance was a hoax. Even if it takes cognitive dissonance, it's possible. We see it all the time with conspiracy theorists, who believe, in spite of blinding evidence to the contrary, that the WTC couldn't have fallen due to the impact of the planes on 9/11. Sure, there are crazy folks among their number, but not every Truther is crazy. They could simply choose to believe what they want to believe.
