What should be teach in schools

When I was a child, I didn't even knew what was being heterosexual. It wasn't until I grew up that I started to know about LGBT+ community. Now here is my point, how is going to feel normal someone that feel themselves like the other genre or that likes its same genre or that don't even like any of them? How? If all their lives have been taught that girls like boys and boys like girls. That your body determines what you are. That you have to fall in love in a romantic way with someone. I think this is wrong, it's wrong that a little kid has to be confused on how to feel just because we live in an homophobic society. If we teach kids to see this as normal, that this is right, there would be less confused people in the future, and I'm sure that people would be a lot more respectful to this community, the respect that this people deserve, that we deserve. All humans, it doesn't matter where they come from, what age do they have, genre or another thing, we are all people, and we need to learn how to support each other. I really think that this is an important thing to teach, because I realize that schools teach us a lot of things, but none of them are how to face the real world. If someone, when I was a child, would've come to me and said that it was ok to like a girl or a boy, and that this didn't had anything wrong, I would feel more safety, less ashamed of who I am and I wouldn't feel so scared. Scared from what people say, and it wouldn't have taken me so many years to realize that I'm bisexual, that is completely something normal and that I don't have to hide it. If we teach kids all this, we wouldn't have to fight so strong to have the rights we deserve. But unfortunately, schools don't teach this and because of that, it is our duty to do it, with our cousins, nephews, sons and daughters, until the day that, a day that I really hope comes soon, all these kids become adults and can know and accept this reality.
