I cannot imagine how Tibetans would feel having their identity stripped.
The reality is that there is literally none or very little part of the civilized world (can anyone name a couple) that is very pure in its identity. I do not now of any country in the civilized world that has not experienced a blend of cultures as a result of being conquered or via peaceful assimilation. China for one, cannot claim to have only a single identity. To that end, I am not sure if there is all that much to preserve in an identity.
If removing the Tibetan's identity and minority status means a complete removal of what makes the Tibetan a "minority"and what alienates them from the mainstream, perhaps it is a good move. Like Hope Rainbow said, there are places in the world where people fight to have their identity as minorities removed.
I would say that a people's identity is not given by a piece of document and neither can the removal of that same document erase a nation's identity.
To the rest of the world, the identity of the Tibetan is one of a people who are steeped in their spiritual beliefs and culture. People who are loyal to their religion and their Guru. I know the statement I just made is superficial at most because I hardly know the Tibetan culture, but the harsh reality is that all of us,from every race and culture....we must all evolve and change. If not to political pressure, then change must come from the passing of Time.
I feel for the Tibetans but there is such a great opportunity for them now to influence the most populous country in the world, through their unique brand of Tibetan Buddhism. If it means to "lose" their identity only to give identity to Buddhism around the world, then perhaps it is worth it.
I'll say more on this.
Ethnic identity or not in official papers.
What makes one a Tibetan is NOT what is stated in the ID, it is what is being practiced every day, every moment.
To strip spiritual practitioners of their holy practice of Dorje Shugden, THAT is a very serious action affecting someone deeply. Compared to the removal of a mere title in ID papers, there is no way to even start...
I am not a Tibetan, and will not want to state FOR or AGAINST the removal, it is not my battle. I can only say what I think about it.
What I think is this: instead of focusing on a title, let's focus on spiritual practice, let all Tibetan be serious, genuine, sincere practitioners of their spirituality, whichever school they belong to. In doing so, they'll have a real "identity", and if they can do that without conflicting with the whole of China, they'll even create causes for the whole of China to practice, they'll generate great amount of merits, they'll give back the shine and grandeur to Tibet as seen by Chinese other than Tibetan chinese.
I think that is more important than to battle for a title. The government in China can easily remove the title especially if they see that it triggers some "national pride", for they would see that as a potential threat.
Let's not forget that the world, generally, sees Tibet as a place of spirituality while the Chinese governement and a large number of the Chinese (other than Tibetan Chinese), see Tibet as a potential danger that may trigger instability, civil war, even terrorism. Tibetans can change that and show that the Tibet province of China is not a threat, but a spiritual beacon, a spiritual pride for the whole of China and the whole world. If there is one way for Tibetan to "restore" their identity, I think that is the best way and the most rewarding AT EVERY LEVEL.
We are in 2012, we are no more 1950, things have changed, "national" romanticism and nostalgia can only bring about problems.
Sincere spriritual practice can only bring about solutions AT EVERY LEVEL.
What's more, China is now promoting the practice of Dorje Shugden, making the Tibetans in China more free than the Tibetans in exile when it comes to the practice of Dorje Shugden.
Ironic isn't it? (so maybe HHDL did free Tibet eventually...)
