I wouldnt call a Burmese killer a Buddhist, anymore than Id call a Taliban fighter a Muslim. Anyway, its all a case of perception, isnt it? In areas like Pakistan, etc., Muslims are the aggressor. In Burma, Muslims are the victims. In Afghanistan, with Bamiyan, Buddhists were the victims. In Burma, Buddhists are the aggressors. The point is that just because you possess an ideology and are fundamentalist about it, doesnt mean that you are its top practitioner or your actions best capture the essence of your belief.
The same thing is happening in the case of Dorje Shugden, its all perception. Before the ban, the perception of Dorje Shugden practitioners was that their such great practitioners by following their gurus instructions. After the ban, the perception now is that Dorje Shugden practitioners are spirit-worshippers and condemned to the three lower realms.
Politics change, trends come and go, and opinions are forever shifting. The only thing that remains constant is your gurus advice and compassion to help you, so why not just go with what he says?
