I think we should remind CTA to exercise what the Dalai Lama has been telling them all along. The Dalai Lama wants CTA to practice democracy and have elections and even the Dalai Lama resigned and had a lay Kalon Tripa elected democratically to take over power. Isn't the Dalai Lama's message very clear?
CTA should practice what they have been taught. Everywhere else in the world, they are electing their leaders and the leaders are putting into place policies that they had promised their people. It is these policies that shape people's opinion on whether or not to vote for the aforementioned leaders into power. The very fact that the Dalai Lama resigned, he has already placed the power back into the people's hands.
If the CTA really wants to have control of Tibet again, they should start by uniting its own people. This ban has fragmented Tibetan society to its core. Monasteries have split, a sizable segment of society is ostracized and people are living in fear of who they are associating with. All this is happening because of their religious views? That is such a violation of basic human rights! How is CTA going to get Tibet back when it is running an imaginary state in India with such divided people? If I was China and I wanted to hand Tibet back to the CTA, I would take a hard look at CTA, laugh and change my mind.
Therefore, archaic policies like this ban (no offense to the Dalai Lama) that divide Tibetan society, they should chuck out quickly and enforce newer policies that foster harmony and religious tolerance. We want a united Tibetan people so the real dream of CTA can be realized.
