I'm afraid your another victim of the deliberate erasing or unreporting of us in history and anthropology. Let me give you some examples which you can look further into. Don't take my word on it, the information is out there to corroborate all these it's just not talked about.
Samoa: accepted and valued part of society. The Fafafine (and there are multiple spellings of that) are a 'thrid sex' of crossdressing males which look after the house and children of their extended families and are most mens first sexual experience!
Tonga: Accepted and valued part of society. At coronations of the king and royal marriages it is a crossdresser who arranges the celebrations! (there is footage of this from the last Royal marriage in an old thread in the media section!)
Native America: many tribes had MtFs and FtMs as extremely sacred, often shamans. Some of the chiefs famous to white america regularly consulted CDs for their advise.
Ancient Greece: was accepted and sacred. The Cybaline faith for example was made up entirely of MtF priestesses who were castrated as a primitive form of SRS
Ancient Scythia: Accepted and sacred. The main faith was the goddess associated with horses. The priestesses were MtF who not only were castrated but drank the urine of pregnant mares for their hormones. They also had warrior women of high rank. They defeated Rome on several occassions!
That's the tiniest tip of the iceberg. Examples can be found amongst cultures right around the world and right throughout history. So you couldn't be more wrong about acceptance but with the silence on the subject thats hardly your fault.
The fact is that acceptance has been common throughout human history. UNacceptance instead is in much of the world quite new!
