Bahai teachings clearly and unequivocally state that homosexuality is evil, immoral, a shameful aberration, an affliction, a handicap that is against nature, that should be purged from the world (all words taken from Bahai teachings).
This has nothing to do with whether gay Bahais should be able to fulfil their true nature (which they cannot) or suppress their innate self (which they are required to do).
FYI, Baha'is do not believe that the true nature or innate self of a human is sexual, we believe our true nature and innate self is spiritual.
The following is a post that was posted by Dale on the Planet Baha'i forum years ago. I liked it so much that I saved it in a Word document. I asked Dale if I could pass it on and he gave me permission to do so. I won't say that this is the 'official' Baha'i position, but it is my position.
"Ah, but that is conflating love and sex (which, yeah, people do all the time). Sex is not love and love is not sex, nor is there any necessary relationship between the two. In human beings it is true that sex typically plays a bonding role in a certain type of loving relationship, but it's not necessary to it (however much people think it is). We love lots of people who we would (unless something is wrong with us) never consider having sex with: children, parents, close friends, etc. One might even add household pets to the list.
Sex is
primarily about reproduction. That's why it even exists in the first place. It's a biological mechanism that increases diversity in the gene pool, for one thing. Its role in relationships in
some species is a secondary role, not the primary one, which evolved much later. Sex is not something only cute furry creatures do for bonding. Reptiles and amphibians and insects and even plants have sex lives. It evolved as a means of reproduction, and only later acquired secondary roles. Those who want to divorce it completely from its primary role (and they do exist; I've been in discussions where people have argued quite strenuously that sex isn't about reproduction at all!) are in a very real sense attempting to force it to conform to their own selfish desires . . . and that, ultimately, is what is against our spiritual nature.
Our spiritual nature cannot be developed except by "dying to self" and "living in God." God has given us a dual nature: one material and one spiritual. Sex is part of the material nature, however much it may be able to play a role in a truly loving relationship. It is not what we
are, even though people insist that it is. (Extreme but real example: I read an article in the long ago when the AIDS epidemic had become the big news of the day in which the author, a promiscuous homosexual who had contracted the disease, wrote about how it had affected his life. He stated near the end that he had to take a lot of precautions now to avoid spreading the illness, but that he couldn't give up his promiscuous lifestyle because that was "who he was.") God is calling us to struggle against our lower nature and to become who we truly are: not material beings, not sexual beings, but
spiritual beings who are in control of the physical side of our nature and who can thus find true happiness living in conformity with His will. Although not scriptural, there is a possible explanation of why He has made it so hard that I ran across long ago in a Baha'i children's book: Because if it were too easy, it wouldn't be worth anything. Or put another way, because only by being challenged can we really prove our love for God."
