I think Deb may be onto something when she talked about a false trib/AC at http://www.fivedoves.com/letters/march2013/deb312.htm . Getting Christians to "cry wolf" would be a very effective way to cause people to disbelieve the real thing when it finally comes. And while I don't think "Zero" is the REAL false messiah, I do think it is possible that he is being used as a false AC to get believers to cry wolf about him and thereby discredit those who have awareness that such a thing will come. He's a decoy, not the real McCoy.
One thing we know about the REAL FM / AC is that he will not acknowledge ANY G-d as a higher power since "Neither shall he regard the gods of his fathers...nor any god...for he shall magnify himself above all. " (Dan 11:37). He won't pretend to be a Christian. He won't pretend to be a Muslim. He wno't pretend to believe there is a higher power above him. He will try to convince the world he is THE G-d, and he could not do that if he EVER, at ANY moment in his life, recognized a higher power than himself. Such a recognition would be an admission he is not an omniscent being. The real FM may sell that in a way modern populace will accept, such as claiming to be the reincarnation of Yeshua, and the reincarnation of Buddha, etc......but he will NEVER pretend to belong to a religion that recognizes a power higher than him.
Shalom,
