It does not exist. It exists nowhere in the muslim world. Their religion says so....so it must be. Of course if a gay person is found, death is immediate. Except in Iran. It seems that nowhere in their religious book (which, in some ways, dates back a zillion years before the Dark Ages) nothing is said about sex change operations. Wonder why.So: if not prohibited, as a million other things that make life bearable, then it is permitted. This taken care of, they figure that inside every gay person is a woman wanting to get out (In the investigative reporting I saw on CBC a few years back, nothing is said about lesbians). So the gay person is given a choice: go for the operation....or die. Not always a great choice but the alternative being death, what would you choose?
