I'm still a newbie and there's much I don't know about but I tend to agree with the viewpoints of Ensapa and Rinchen.
By "banning" Dorje Shugden, H.H. Dalai Lama has propelled Dorje Shugden onto the world stage, especially in China where DS's presence is sorely needed, even if it means HHDL will take on the "ugly" role in front of Buddhists all around the world. Isn't that a move of compassion and selflessness?
As for those who take it upon themselves to do harm to DS practitioners, I greatly doubt that HHDL actually told them explicitly to deliver violence. Everyone has a choice and true dharma practitioners should know better than to interfere with other people's practice. If anyone wants to exercise the ban, they should apply it to themselves, full stop. Which means, this whole "ban" is a perfect exercise to separate those who really practice dharma from those who only desire to politicise dharma.
Then again, these are only the views of a newbie...
