Hijra is a classification of gender (known as a third gender), found in South Asia. Typically, they are males who take on a female social identity but are neither male nor female. This does not always imply that they are transexual.
Hijra =/= Transexual. They are born that way.
And contrary to popular Western beliefs about them, they don’t need operations. They need recognition as Pakistani (and other south asian coutries) citizens and all the rights that they fully deserve.
Very similar to Fa’afafine people in Samoan culture.
