transgender in Thailand

Through watching this video, I thought Thailand is free country in that many transgenders live openly compared to any other countries. What I was surprised is the government of Thailand established new constitution, ensuring that Thainland would have transgender and gay rights for the first time in its history. It is quite unique constituion that few people come up with. But then, does it mean that transgenders hadn't had rights before this constituion was established? I doubted it. Transgenders should have rights since they are born just like us. So I suppose that the background of establishing this constitution shows that there are still kind of a prejudice against them even we don't realize it.
