Skillful. Encouraging focus on training the mind is important.
In dialogue about the controversy, the most essential point that should be continuously revisited and reminded of is that a mere difference of religious opinion is not a valid reason to persecute people. People are welcome to disagree about Dorje Shugden, but people often get lost in debate and miss the basic point. Who Dorje Shugden is or isn't is completely irrelevant when we're talking about basic human and religious rights.
It doesn't matter how Lhamo Dondrub came to his decision to ban the practice. The ban and abuse of rights is wrong. That so-called "Buddhists", supposed expert logicians, and people who generally have common sense can't seem to grasp this most basic concept is absolutely astonishing.
Seriously, this whole controversy comes down to this basic concept - Buddha said 'don't harm others, be kind'. Is that an extremely complex philosophical proclamation or complicated formula in rocket science? No. Yet supporters of Lhamo Dondrub continually defend human rights abuse. So how can these people even consider themselves to be following the Buddhist Way of Life? That they continually deny the overwhelming evidence of abuse as well as how the ban contradicts the most basic Buddhist view indicates a serious degeneration of the Buddhist tradition. This complete loss of common sense and ability to see reason should continuously be met with common sense and basic sound reasoning, just as the Buddhas tell us the same thing over and over in hopes we'll eventually get it. So Kadampa Ryan is trying to appeal to these people's common sense or reason. I'm sure this attempt has the applaud of the Holy Beings. Good job, keep it up.
