I was wondering, when someone became a covenant breakers the guardian told the bahá'ís not to talk to them. Isn't that the same as what the muslims are doing now telling people not to talk to bahá'ís because they are dangerous people.
A major difference is that in our case, it is part and parcel of Baha'i law to not have any interaction with them. I'm not sure if there is an explicit prohibition of associating with those who come to accept someone after Muhammad either in the Qur'an or an authentic hadith. I think it's just a principle that the Iranian Muslims came up with on their own.
Let's say that someone in 500 years comes and sais he is the next manifestation. What will the bahá'ís do. More and more people start following this person. Will the Universal House of Justice keep the union of all religions? Even this new one?
Why even go so far as 500 years? There is already one Iranian-Australian ex-Baha'i who laid claim to prophethood of some sort not too long ago, though he is now an Azali more or less. Even while Baha'u'llah was still alive, his own son - Mirza Muhammad-Ali, not `Abdu'l-Baha - laid claim to be a Manifestation of God, and it is said that Baha'u'llah slapped him for that.
Thus, there will probably be more people in the future who will make claim to that same station before 1,000 years has passed, and whatever fruits they produce would not be part of our "unity of all religions" principle, because the implication behind that is the
divinely revealed religions (i.e. Hinduism, Buddhism, Zoroastrianism, Sabeanism, Judaism, Christianity, Islam, the Babi & Baha'i Faiths as well as the other unknown ones which have been lost to time). Therefore, we generally do not consider other groups like Satanism, Cao Dai, the Moonies, etc to be belief systems derived from God. Similarly, such a premature post-Baha'i faction which obviously violates the Aqdas would fall under the same category.
The House of Justice does have a letter regarding the recognition of the next Manifestation:

It's said in the bahá'í faith that the next manifestation woun't come until at least 1000 years after Bahá'u'llah. So this person can't be a manifestation. This is just like what the muslims are saying now, that Bahá'u'llah can't be a prophet because Muhammed was the last one.
The difference is that, from the Baha'i perspective, there is a lot of leeway for the terminology and context of Qur'an 33:40, most importantly the term "Seal of the Prophets" (Khatme-Nubawwa or Khatammo-Nabi). For example, refer to the following scholarly papers on the subject:
A Baha'i Approach to the Claim of Finality in Islam
Six meanings associated with the terms seal of prophets
Baha'u'llah, on the other hand, gave absolutely no room for leeway or anything but a clearly literal interpretation with regard to the 1,000-year injunction:
"Whoso layeth claim to a Revelation direct from God, ere the expiration of a full thousand years, such a man is assuredly a lying impostor. We pray God that He may graciously assist him to retract and repudiate such claim. Should he repent, God will, no doubt, forgive him. If, however, he persisteth in his error, God will, assuredly, send down one who will deal mercilessly with him. Terrible, indeed, is God in punishing! Whosoever interpreteth this verse otherwise than its obvious meaning is deprived of the Spirit of God and of His mercy which encompasseth all created things."
(Baha'u'llah, Gleanings from the Writings of Baha'u'llah, p. 346; Emphasis added)
So of corse bahá'ís are persecuted, in the eyes of the muslims they are covenent breakers and you shouldn't talk to these kinds of people. Right?
I'm just trying to imagen what the bahá'ís would do if they were in the same shoes as the muslims in Iran are now.
If Iran were not a hardliner theocracy and people were actually able to express their opinions and practice freedom of and
from religion there, the Iranian Baha'i scholars could present their perspective on the "Seal of the Prophets" and engage in constructive dialogue with Muslim believers. But in Iran's current state, such a scenario is merely a pipe dream. I find it ironic that the Qur'an actually speaks of there being no compulsion in religion, but then one can look at Iran's leadership as well as their treatment of their country's minorities and be staring in the face of the ultimate antithesis of that verse.
Always remember that the first Babis and Baha'is were Muslims. Vahid Darabi was undoubtedly the most learned Iranian scholar of Shi'ah Islam at his time, having memorized over 30,000 Islamic hadiths. Yet, for such a learned individual, this "Seal of the Prophets" deal was obviously a non-issue, as he became an ardent Babi after interviewing the Bab three times on orders of the Shah and was eventually martyred. The Hands of the Cause of Baha'u'llah were all prominent mullahs.
Later, Mirza Abu'l-Fadl Gulpaygani - another brilliant Islamic scholar who studied at Al-Azhar, the most prestigious Islamic school in the world - not only became an even more brilliant Baha'i after an amusing encounter with a Baha'i blacksmith, but was essentially the first Baha'i apologist. Imagine: an extremely learned Muslim eventually became a Baha'i and wrote texts which eloquently defend the Baha'i Faith and its doctrine (e.g. The Brilliant Proof, Miracles and Metaphors, and the Kitab al-Fara'id). What a leap of faith he had to make to get as far as he did! `Abdu'l-Baha even said once that Mirza Abu'l-Fadl was like himself ("nafse man hast"), a practically unparalleled honor in early Baha'i history.
In the later 20th century, a very learned mullah named Shaykh Muhammad Muvahhid decided to research the Baha'i Faith, but he did not intend to do so dispassionately - he was out to see what obvious flaws he could find in our religion. So he went to a library which happened to have the Kitab-i-Iqan, which he read and began reading. His initial mindset of mockery soon changed into bewilderment and fascination with what he was reading, and he, too, came to accept Baha'u'llah. Yet another prominent cleric! And he even brought another
19 mullahs to the Faith before he was abducted in May 1979.
I hope all of this helps.
