Sharing Our Innermost Thoughts

I come across thousands of post asking for the rights of third gender. I believe that instead of posting on social media platforms we should inculcate this in our education system.
Just pick up a book of a nursery child, or any other class and you will never find anything about the third gender. Our education system never taught us about third gender. I was shocked when I heard that people get feelings for the same gender; it would not have been that much shocking if I would have been taught about all this in my school.
