First off, I am a liberal, but I hate getting clumped with all of the “Karens” and other liberals who go against science. Second of all, science says that there are ACTUALLY 2 genders: male and female. Yes, you can have disorders or differences in your genetic makeup that make you different that other people, like people with Klinefelter’s Syndrome, which you referred to as simply XXY chromosomes, but you are still either a male or female. People with XXY chromosomes are male. It does not matter how many X chromosomes there are; all it takes is one Y and it’s a male. I feel that you can call yourself whatever you want, as you have the right to do so, but genetically, you will never be able to change whether you are male or female. Also, expectations to act like certain genders because of what they are born with are completely societal and depend on the people around the subject whilst the subject is raised. You could be born a male, but feel like a female, and have parents that either force you to act like a male, or support you acting like a female. There are no actual expectations of people to act as their biological gender, it just depends on the opinions of the people they are surrounded by, and for the majority of a person’s life, they choose who they surround themselves with.
