The short answer to your question is yes. There were many tribes in which male homosexuality and/or lesbianism was common. In fact the french settlers had a separate word to refer to Homosexual Native Americans. And yet another one for transvestite Native Americans which iin several tribes was not in any way associated with homosexuality as it it generally is today. An equally intriguing question is whether a reservation could choose to recognize gay marriages. In some ways the tribes are sovereign but in a number of ways they are not. We could for instance ban non natives from our reservations altogether. But assuming that you are let on many of the laws of the reservation do not apply. We cannot for instance stop you from hunting or fishing on the reservation. But why does that not really surpise me? You guys never sis listen to us when it came to gun titin'.
