Christianity, Judaism and Islam are independent religions which, although they cross in certain areas, are essentially self-contained and requiring no updating by Bahai’s in the attempt to convince people of their progressive revelation. That in simple fact is the Baha'i attempt to replace Jesus with Baha'u'llah as the new Christ, and to replace all previous world scriptures with the Baha'i writings as the only true guidance for the entire human race, at least for the rest of the millennium until another messenger comes along.
As you told me, if I want to know about Christianity I should read the NT. I think that the same applies to you. Rather than listening to Bahai zealots on a religious forum to inform your opinion regarding the goals of the Baha'i Faith, you should read what the Baha'i Writings say about that. I have read the primary Baha'i texts so I know well what those goals are, and they are not what you seem to think they are. At the very least, I think you should read what the Baha'i Writings say about the fundamental purpose of the Baha'i Faith.
“Let no one, however, mistake my purpose. The Revelation, of which Bahá’u’lláh is the source and center, abrogates none of the religions that have preceded it, nor does it attempt, in the slightest degree, to distort their features or to belittle their value. It disclaims any intention of dwarfing any of the Prophets of the past, or of whittling down the eternal verity of their teachings. It can, in no wise, conflict with the spirit that animates their claims, nor does it seek to undermine the basis of any man’s allegiance to their cause. Its declared, its primary purpose is to enable every adherent of these Faiths to obtain a fuller understanding of the religion with which he stands identified, and to acquire a clearer apprehension of its purpose. It is neither eclectic in the presentation of its truths, nor arrogant in the affirmation of its claims. Its teachings revolve around the fundamental principle that religious truth is not absolute but relative, that Divine Revelation is progressive, not final. Unequivocally and without the least reservation it proclaims all established religions to be divine in origin, identical in their aims, complementary in their functions, continuous in their purpose, indispensable in their value to mankind.”
(The World Order of Bahá’u’lláh, pp, 57-58)

Fundamental Principle of Religious Truth

I agree that the older religions are essentially self-contained and require no updating by the Baha'i Faith, but as noted in the passage above, that is not a goal of the Baha'i Faith.
Baha'is should not be attempt to convince people of progressive revelation because Baha'u'llah wrote that the faith of no man should be conditioned by anyone except himself.
No, it is absolutely NOT a simple fact that the Baha'i Faith is attempting to replace Jesus with Baha'u'llah as the new Christ.
Baha'u'llah never claimed to be Christ, only the fulfillment of the return of Christ as promised in the Bible.
It is untrue that the Baha'i Faith is attempting to replace all previous world scriptures with the Baha'i writings as the only true guidance for the entire human race. The divine qualities and the eternal commandments of every true religion will never be abolished; they will last and remain established for ever and ever. The foundations of the Religion of God, which are spiritual and which are the virtues of humanity, cannot be abrogated; they are irremovable and eternal.
“the Law of God is divided into two parts. One is the fundamental basis which comprises all spiritual things—that is to say, it refers to the spiritual virtues and divine qualities; this does not change nor alter: it is the Holy of Holies, which is the essence of the Law of Adam, Noah, Abraham, Moses, Christ, Muhammad, the Báb, and Bahá’u’lláh, and which lasts and is established in all the prophetic cycles. It will never be abrogated, for it is spiritual and not material truth; it is faith, knowledge, certitude, justice, piety, righteousness, trustworthiness, love of God, benevolence, purity, detachment, humility, meekness, patience and constancy. It shows mercy to the poor, defends the oppressed, gives to the wretched and uplifts the fallen......
These divine qualities, these eternal commandments, will never be abolished; nay, they will last and remain established for ever and ever. These virtues of humanity will be renewed in each of the different cycles; for at the end of every cycle the spiritual Law of God—that is to say, the human virtues—disappears, and only the form subsists .......
These foundations of the Religion of God, which are spiritual and which are the virtues of humanity, cannot be abrogated; they are irremovable and eternal, and are renewed in the cycle of every Prophet .......
The second part of the Religion of God, which refers to the material world, and which comprises fasting, prayer, forms of worship, marriage and divorce, the abolition of slavery, legal processes, transactions, indemnities for murder, violence, theft and injuries—this part of the Law of God, which refers to material things, is modified and altered in each prophetic cycle in accordance with the necessities of the times.”
(Some Answered Questions, pp. 47-48)
Baha'is believe the former religions have fulfilled their purposes and that the Revelation of Baha'u'llah is the latest revelation from God which was revealed for what humanity needs in the present age.
“And now concerning thy question regarding the nature of religion. Know thou that they who are truly wise have likened the world unto the human temple. As the body of man needeth a garment to clothe it, so the body of mankind must needs be adorned with the mantle of justice and wisdom. Its robe is the Revelation vouchsafed unto it by God. Whenever this robe hath fulfilled its purpose, the Almighty will assuredly renew it. For every age requireth a fresh measure of the light of God. Every Divine Revelation hath been sent down in a manner that befitted the circumstances of the age in which it hath appeared.”

Won't happen, even if they do get their war.
Only God knows what will happen in the future because only God has perfect foreknowledge.
