The essence of the situation:
Regardless of who he is, according to worldly conventions his actions are inappropriate and must be stopped. Even if the ban remains in place, it is the active persecution of others that must stop.
Regarding view:
If we learn to regard everything that appears to our mind as a dialogue between us and our Guru that functions to refine our consciousness, we understand that the Guru (our own Buddha nature itself) is constantly requesting us to respond appropriately to what is appearing. Appearances should stimulate the correct views of Sutra and Tantra within our consciousness, that is all. The only "right view" to have of other people are those views contained in Sutra and Tantra, you choose. Either way, the meaning of your life is being seized. This is the most important point.
In Dorje Shugden kangso it says:
"To tame disciples, you perform deeds beyond ordinary understanding,
Appearing as if in a drama as gods, spirits, demons, or deluded beings,
Or as men, women, handicapped people, or even insane beings;
I rejoice in your great kindness towards the doctrine and living beings."
Key words - "to tame". Are you being tamed through applying your Gurus instructions to the appearances of this controversy?
To those who have the DL as a Guru, consider this: Venerable Geshe Kelsang Gyatso Rinpoche once said that Vajradhara appears in an ordinary human aspect so we can relate to him, and that of course he will appear to us to make mistakes. He then said we need to act appropriately and confront our Guru with questions if their behavior does not seem appropriate by normal conventions.
If my Guru is beating someone to death, I will stop them. Though myself and the recipient of the beating may have pure view, if with my eyes I see a human beating a human, that is ordinary appearance, and according to ordinary conventions beating someone to death is inappropriate. So though you may regard the DL as a holy being, it is entirely appropriate to confront him regarding his extremely inappropriate behavior. So what is the view then? Though you may see him as holy, you also see much suffering and develop compassion for the beings he appears to be inflicting suffering on, and you take steps on their behalf just as Jetsun Marpa's wife and disciples pleaded with the Master on Je Mila's behalf.
Otherwise, the DL is a suffering living being, and out of compassion we must take actions to try and stop him from creating immense suffering for himself and others.
Whichever view you have, you can still take action to stop the inappropriate behavior and suffering, even if it is only through prayer. Regardless of who he is, according to worldly conventions his actions are inappropriate and must be stopped. Even if the ban remains in place, it is the active persecution of others that must stop.
