To me, the depiction of such images make no sense at all and it only goes to show that they are insecure about their own lineage and their own teachings. If their teachings are really that powerful and effective, then they do not need to create anti Dorje Shugden practices, chakras or images as their existing practices would already be powerful enough to ward Dorje Shugden off, that is seeing from their point of view that Dorje Shugden is bad. To be honest, the other lineages such as Kagyu or Sakya do not create such deities to "defend" against Dorje Shugden, nor did they need to modify their Dharma protectors for that purpose. Even the other lineages such as Palyul do not have that Dorje Drollo with the extra Dorje Shugden beneath, only the Dudjom has. Not to be rude or anything, but to the learned, it just shows insecurity.
What is the point of the whole fear of Dorje Shugden thing that is going on anyway? It would be an indirect way of saying that "My lineage is insufficient and not powerful enough to handle Dorje Shugden, therefore I need to create ways to show that he is inferior and to create new practices to ward him off so that my own lineage can grow". It indirectly means that their lineage does not contain enough teachings or is not powerful enough to ward of the "dangers" of Dorje Shugden and therefore they have to create something to stop Dorje Shugden. Why not be confident of your own lineage and practice, and pay no heed to Dorje Shugden and not be paranoid about him? Penor Rinpoche seems okay with Dorje Shugden practitioners and even allowed Shar Ganden to get provisions from them:
http://dorjeshugden.com/wp/?p=2874 and they are doing well and nothing bad has happened to them so far. They dont need a special protector against Dorje Shugden, they just do their own practice (assuming from their angle that Dorje Shugden is)
In the end, I feel, that all of these mud slinging and insecurities are not necessary. What works more effectively is that they prove themselves to be better than gelugpa and that they are not threatened or challenged by Dorje Shudgen and even until today, they have no definite proof that Dorje Shugden has harmed them in any way and yet they choose to hang on to the belief that he did. I hope that one day these images will be restored as since Dorje Shugden is wearing monks' robes which represent the vinaya and renunciation, and wears the domed hat that represents Nagajurna's perfect and flawless teachings, to step down on Dorje Shugden is to also step down on these two aspects of Buddhist teachings at the same time and that is definitely not a nice thing to proclaim.
