The Baha’i Faith has no such law.
I'm sorry, but it's early morning and I haven't drank my cup of coffee yet and forgot to post the details.
So here it is:
Iran: In accordance with sharia law, homosexual intercourse between men can be punished by death, and men can be flogged for lesser acts such as kissing. Women may be flogged.
Nigeria: Federal law classifies homosexual behavior as a felony punishable by imprisonment, but several states have adopted sharia law and imposed a death penalty for men. A law signed in early January makes it illegal for gay people countrywide to hold a meeting or form clubs. Source
*** But the important detail is what's written below, specifically the last line in bold***
The Bahá’í teachings forbid any sexual relations outside of marriage. “Ye are forbidden to commit adultery, sodomy and lechery. Avoid them, O concourse of the faithful,” Bahá’u’lláh states. In letters written on his behalf, Shoghi Effendi has provided the following guidance:
Concerning your question whether there are any legitimate forms of expression of the sex instinct outside of marriage: according to the Bahá’í Teachings no sexual act can be considered lawful unless performed between lawfully married persons. Outside of marital life there can be no lawful or healthy use of the sex impulse…
And:
The Bahá’í Teachings on this matter, which is of such vital concern and about which there is such a wide divergency of views, are very clear and emphatic. Briefly stated the Bahá’í conception of sex is based on the belief that chastity should be strictly practised by both sexes, not only because it is in itself highly commendable ethically, but also due to its being the only way to a happy and successful marital life. Sex relationships of any form outside marriage are not permissible therefore, and whoso violates this rule will not only be responsible to God, but will incur the necessary punishment from society.
You did say that 'from YOUR side of the fence the Prophets of God ARE the Moral Benchmarks or Compasses,' and that, 'like a good doctor, they know what harms and benefits us.'
Unless if you don't believe that Bahá’u’lláh is a prophet of God and/or he is wrong.
