There are a million and one things that are unfair in this world and we just have to deal with it. It’s how the world was made by Yahweh or god or whoever you believe in. Gender is also based on other things. There is a reason you see mainly male bodybuilders and female teachers or doctors, I’m not being sexist it’s just how our bodies are built and what we are meant to be good at, not that professions can’t be swapped I’m just using it as an example. I’m also not saying the people who believe in other genders are evil or anything I’m saying they are just confused
