Persoanally, I am not bothered with a government that is so degenerate. However, the CTA or any organisation that acts as a representative of the Tibetans in exile is important, insofar as to take care of their welfare. Internationally, the CTA is no more effective. Whatever, they are trying to do in Tibet is pass its usefulness. The only thing is to administer the Tibetan in exile.
For that reason, I think all groups and schools of Buddhism, Christians, Muslims, Hindus must have representatives .That brings to another question. Can Shugden be considered another school or even simply have a representative?
