Baha'i claims that it is in perfect harmony with science. Science has evidence that homosexuality is epigenetic/genetic and is found in nature. Yet, traditionally, Baha'i frowns upon homosexuality and says it can be "cured"; as if it is a disease.
How can Baha'i claim to be 100% compatible with science if they condemn something found in nature? Branching from this, can one be gay while in a monogamous, loving relationship and still be accepted as a Baha'i?
Thanks for your question... The following is my own "take" on this issue as a Baha'i...
Harmony between science and religion is a principle of our Faith and allow me to explain a bit what that entails...
With regard to the harmony of science and religion, the Writings of the Central Figures and the commentaries of the Guardian make abundantly clear that the task of humanity, including the Bahá'í community that serves as the "leaven" within it, is to create a global civilization which embodies both the spiritual and material dimensions of existence. The nature and scope of such a civilization are still beyond anything the present generation can conceive.

Also "Science" as you are aware is an unfolding process... rather than rigid dogma. What was considered "scientific" say fifty years ago may not be "scientific" today.. The textbooks are constantly being revised.
The sphere of religion in my view deals more with our own responsibility in this life. The issue of our behaviour then has more to do with our judgements. Knowing people have certain proclivities in some areas and that each person is really unique and inherits various personal aspects together with the social milieu they were raised in still requires in our view choice and judgement which are the province of religion.
The House of Justice has further delineated:
"Man's physical existence on this earth is a period during which the moral exercise of his free will is tried and tested in order to prepare his soul for the other worlds of God, and we must welcome affliction and tribulations as opportunities for improvement in our eternal selves. The House of Justice points out that homosexuals are not the only segment of human society labouring at this daily task -- every human being is beset by such inner promptings as pride, greed, selfishness, lustful heterosexual or homosexual desires, to name a few which must be overcome, and overcome them we must if we are to fulfil the purpose of our human existence."
