Of course the Dalai Lama is still involved in politics. If he was not, and had really given up political power, then the CTA would be able to lift the secular effects of the ban on Dorje Shugden. I mean if we give the Dalai Lama the benefit of the doubt and that he really believes Shugden is the devil incarnate, he has every right to say no Shugden practitioner should come to his teachings. However, he has no right to say that no Shugden practitioner should have access to medical treatment, schools, travel papers, shops etc. Yet this is happening.
Since the CTA has perpetuated this hugely discriminatory practice for so long, despite the Dalai Lama's "retiring" from politics, it is obvious that he is still very much involved in Tibetan politics, even though he is not ostentitiously so. To counter this logical view, the CTA should find its balls and fix this situation immediately and lift the ban!
