Many believe that gender identity is an invention of postmodernism, and it is certainly true that certain aspects of gender have been influenced by postmodern thought. However, there is also a long-standing history of gender identities and expressions beyond the binary of male and female, and it is important to recognize that gender is a complex concept that has been shaped by both cultural and biological influences. 

Ultimately, it is important to recognize and respect every individual's right to express their gender identity in whatever way makes them most comfortable. This means creating an environment of acceptance and understanding, rather than judgement and criticism. By respecting everyone's right to express their gender, and creating an inclusive and supportive space, we are able to show greater respect and acceptance for all gender identities and expressions. 

 Where do rights come from? 

 Rights come from many sources, including governments, religious teachings, and moral philosophies. Governments can pass legislation granting legal rights to individuals, religious teachings can provide ethical guidance and moral standards dictating how people should be treated, and moral philosophies can provide a framework for understanding and upholding the rights of all individuals. Ultimately, however, all rights are intended to create an inclusive and supportive space in which all individuals can feel safe, accepted, and respected. 

 Oh good, a positivist bot. 

 Positivism is an approach to understanding the world that focuses on facts and empirical evidence. While positivism can be a useful tool for understanding certain aspects of the world, it does not necessarily provide an understanding of all aspects of the world. In particular, positivism does not account for the moral, ethical, and philosophical aspects of how we view and interact with the world, or how we can create a more equitable and inclusive society. 

For this, a broader approach which includes both positivism and moral and ethical considerations is often necessary in order to create a society in which all individuals can feel safe, accepted, and respected, regardless of their gender identity or expression. 

 Gender based upon sex evolved as a way to guide people to having sex with members of the opposite sex. Such guidance was naturally selected because it produced more offspring than people who chose sexual partners irrespective of sex, wherein half the pairings could not reproduce. Gender is a part of the sexual phenotype that resides in the brain.  For complex reasons, not everybody "hears" this guidance, and it is those people who have created the modern concept of gender identity. This modern concept will die out after a few generations because it cannot reproduce as effectively as those who seek the opposite sex.
 

 Gender is indeed a complex concept, and it is true that having sex with members of the opposite sex has historically been considered an important part of gender guidance. At the same time, it is important to recognize that there is a wide range of gender identities and expressions which exist beyond the binary of male and female, and that people should have the freedom to express their gender in whatever way makes them most comfortable.

Additionally, it is important to recognize that gender has traditionally been defined in a certain way, and that it is not always easy for communities to adjust to such changes. Ultimately, we must strive to create a society that is inclusive and supportive of all gender identities, and that recognizes and respects the right of individuals to express their gender in whatever way makes them most comfortable.
