This is just shameful and a direct effort to censor opinions in public. This is what the CTA is... if you go 'against' them for having a separate belief (in this case, our choice of religion which is private in nature, but they make it their business)... then they will do all sorts of nasty things to silence you. Like in this case, that man is obviously an American, asking a fair question (which they didnt allow him to finish asking), but instead of getting a clear explanation or at least listen out of courtesy... they threaten him with arrest and dragged him out of the hall as if he is a criminal. Just like they wrote in their 'government' website, stating Shugden practitioners a 'criminals in history'... guess they're proving their point here.
The CTA needs to be less corrupted and think more for their exile Tibetans. Now it only appears that they're thinking for themselves and are extremely lazy in doing their job. They want the 'power' but don't take responsibility for it.
There are many cases in the past where Tibetans were forced out of exile! They've already been exiled once from Tibet, and when the Shugden ban came along, they were exiled from their exiled community... I am surprised that Tibetan Shugden practitioners are not bitter and sad. Take for example Guru Deva Rinpoche, whom was forced out of India to Mongolia because of the Shugden issue... and Serkong Tritu Rinpoche, had to leave for Taiwan... and HH Trijang Rinpoche had to leave Gaden because of the Shugden ban.
The ban only brought destruction and suffering... but at the same time, it forced all the lamas to go to various foreign countries, and there they taught the Dharma. I hope tha ban will end soon... it is very disappointing to see so much discrimination and religious bigotry in this modern century. We've come so far in terms of morality and human rights, it is a shame to see this happening to a class of Buddhist practitioners.
