So it seems that the Dorje Shugden issue is taken out from the political context, and it now becomes a purely religious issue.
In the political context, it is easy to see that the suppression and ostracization of Dorje Shugden practitioners are wrong in the "worldly sense", and also it is good that we see the political oppression geting less and less.
The religious part is more difficult to fight, because as a spiritual leader, a person can say anything and decide what is to be practiced and not to be practiced and there are much lesser ways that one's decision can be challenged, except for quoting from previous/other spiritual leaders' texts, experience, reasonings.
Nevertheless, as more and more people practice Dorje Shugden and receive positive results, it is a very strong case to support that Dorje Shugden is RIGHT, therefore we all should work hard to promote Dorje Shugden practice even further and wider, and it is a direct counter to false accusations.
