Antichrist has been described in Christianity as one who shall fail to recognize the close relationship Jesus enjoyed with God, the father and son relationship. One who does not believe in Jesus Christ and his stated doctrines will be termed Antichrist.
Kalki avatar the savior, messiah of present times (God manifest in human form) as per Hinduism scriptures shall lay bare the fallacies of Christianity (not necessarily Jesus Christ), as there were not many who could successfully follow teachings of Jesus Christ in toto. Most of the teachings of Jesus Christ available in open market are a mixture of truth and misunderstanding.
Most of the interpretations of writings of Jesus Christ are wrong. Jesus Christ was a spiritual traveler of a very high order. Unless we reached the same mental wavelength, we could not rightly interpret his teachings. Ever since coming of Jesus Christ there had been very few people, rather none to understand the exact meaning of teachings of Jesus Christ.
It is this misunderstanding in the teachings of Jesus Christ, the wrong interpretations that lead to belief in coming of Antichrist. It is Kalki avatar who shall lay bare all such wrong interpretations. Mounted with power of Bhagavad Gita and also Upanishads (independent spiritual treatises), Kalki avatar would disclose to mankind the fallacies that exist in Christianity as preached by clergy of today. None of the teachings of Jesus Christ are wrong, but interpretations definitely are.
Kalki avatar, the upholder of truth would weigh everything contained in scriptures on altar of truth and only truth. Anything that was misinterpreted wrongly would be laid bare, be it teachings of Christianity, Islamic Dharma or even Buddhist scriptures.
Why blame Kalki avatar, one who shall only exercise power of discrimination, free will to distinguish right from wrong, truth from false.
