In current situation, I think the CTA are confuse on which flag to fly.
They are in India, but they fly Tibet flag as it is they are an independent country. So far i have not seen a refugees camp in the world fly their ethnic's flag in the country that host them.
If the CTA "truly" support and followed H.H Dalai Lama to have middle way policy towards the China, the CTA should start fly China's flag and educated their refugees not to scold people using "china dog".
