I don't see any reason to discriminate against these people. They are different from us in a way that they are woman, but inside, is a man or a man but inside is a woman. That is just the difference. Rest, we are all just the same. Well, I could say these things maybe because I'm not a trans gender.
Trans gender people have a lot more complicated trouble and worries,that we could never imagine. One time, I saw "Haruna Ai", a trans gender talent who used to be a man, but right now is a woman, on TV. I've watched VTR of her young days, and I felt very sad, because she couldn't be herself, since her surrounding environment and people were giving pressure on her.
Crystal may had a experience like this, but she did her best to make a movement on against the prejudice to trans gender. This kind of movement is essential to abolish prejudices against trans gender people.
