Here is a passage that accepts the existence of homosexuals as simply a fact. An ignorant jiva might be born as a third gender or as a man or as a woman. It is significant that the punishment for homosexuality in Manu Smriti is bathing. This suggests that homosexuality is not a major sin.
 

> When the Jiva, who is by nature self-luminous, forgets the Bhagavan,
> the supreme Teacher and the Soul of all souls, and become identified
> with the Gunas of Prakriti, then that Jiva, strengthening this
> identification and attachment through the senses and their objects,
> engages himself in various actions, and bears the ultimate fruits of
> these actions by way of embodiments in wombs that are high or low.
> Sometimes, on the strength of actions of a Sattvika nature, the Jiva
> attains to worlds of light; sometimes by Rajasika actions, to the
> world of men full of sorrows and difficulties; and sometimes by
> Tamasika actions to low worlds of darkness and suffering. **The Jiva who
> is blinded by ignorance, sometimes is embodied as a man, sometimes as
> a woman, sometimes as a neuter.**

Srimad Bhagavata Purana IV.29.26-29

Ramakrishna Math did not have any problem getting the well known homosexual intellectual Christopher Isherwood to write a biography of Sri Ramakrishna.
