Yaaaa.... Someones genders is determined by x and y chromosomes. It has nothing to do with accepted social constructs. Anyone who thinks that science is a myth, potentially has extra chromosomes.
Where the fuck did you get this info from. I think you mean you can have XXX or XXY but they are both disorders due to mutations but the sex organs for XXX are same as female and XXY same as male. They just have developmental delay and are usually infertile. But again you are still either a male or female.
