I really don't think it's fair to treat them differently.
It's not their fault, and I'm sure they have had a hard time dealing with it.
These days,there are many TV performers who have suffered from Gender Identity Disorder.
Thanks to them, many people have come to acknowledge these transgender promblems.
Though, still, there are people that find it hard to undestand their feelings.
I can't imagine how hard it is when it's time for them to tell their parents that they don't feel right in their gender that they were born.
In the society, there are many things that are disadvantageous for them.
It's harder for them to get married, and have kids, and sometimes, they may have a hard time making friends. They overcome many things to live normally.
I think there is a need to make a society where they can feel comfortable.
