Gender isn’t something to be “dealt with” it’s simply something that needs to be understood. Gender and sex are two very different things, sex is the orientation you were born with, gender is how you personally identify and feel about yourself. There are 3 sexes, male, female, and intersex. There are 4 main genders as well, including the 3 sexes and non-binary. Non-binary people don’t identify as male or female, they have their own gender. There are also gender fluid people, who use the pronouns she/him/theirs and they can present themselves as either feminine or masculine depending on how they feel. There are hundreds of terms to describe peoples genders, and the only way to effectively handle it is by accepting people for who they are. Pronouns can vary depending on a person as well, we use pronouns in our every day life (they, we, i, she, my, his, etc) and just because people want to be called something they weren’t born as doesn’t make them any less valid, it just makes them different.
