Bahá'í claims strict, unitarian monotheism that is incompatible with the religious symbols it adorns the outside of its places of worship with, some being polytheistic, others dualistic, others trinitarian monotheistic, others even atheistic.
Bahá'u'lláh had three wives but Bahá'í forbids polygamy.
Bahá'u'lláh claims to be the solution to all eschatologies of all manner of religions at the same time, i.e. 2nd coming of Christ, etc.
Bahá'í claims unity of religion but it forbids monasticism, ascetism, ritualism, clergy (yes), confession, pulpits, alcohol, head shaving, begging.
It also forbids personal interpretation, as only texts written by Bahá'u'lláh, as well as further interpretations by `Abdu'l-Bahá, and Shoghi Effendi, heads of the religion after Bahá'u'lláh's death, as well as legislation by the Universal House of Justice, are allowed.
Again, if people think a pope and a bunch of bishops determining what is good or what bad isn't a positive thing, there you will see that there isn't even a clergy, it is a form of hereditary oligarchy over all theology.
Bahá'í is the religion of money. That's how they get their massive funds:
- Huqúqu'lláh, the "Right of God", is a law which requires Bahá'ís to pay 19% of their surplus net-worth (i.e. those things that they do not need to live comfortably), after the discharge of all debts.
- If someone comes upon a treasure trove, one third of the treasure is the right of the discoverer, and the other two thirds is the right of the House of Justice. This law is designed for a future state of society and these matters are currently covered by the civil law of each country.
- Dead Bahá'í must be buried while wearing a ring bouth from the aforementioned oligarchic assholes.
Bahá'í claims to continue the diversity of culture, but it wants one religion, one language, one government, one education, one code of law, one parliament, one police, one currency. The New World Order is its very theology. Tower of Babel anyone?
