In the first place,CTA is not running a democracy despite having a democratic constitution. It's practicing autocracy in governing the Tibetans in exile. It does not welcome diversity of views. Take for instance, it decides to use the ban on Shugden practice to segregate the Shugden practitioners and persecute them. Everyone in CTA has to support this as well as the violence against Shugden practitioners. When a member of parliament like Lukar Jam opposes this, even though they present very logical and reasonable views, they are violently persecuted!
With no 'eligible' candidates to run for election, except the CTAs and their cronies, how will any election ever be democratic?
