From the evident and comments provided, it seems that they are promoting what they themselves think as right and not in a very dharmic way. For example, they talk about tantra which is not suppose to be discussed in public on a detailed way as only the initiated can have this knowledge. Otherwise, it may cause harm to the uninitiated.
On Shugden, they do not allow discussion on this. However, referring to Dorje Shugden as gyalpo makes me uncomfortable and it is derogatory. However, they are just repeating how the Dalai Lama refers to the Protector. Sad. My conclusion is that they are predominantly Nyingma (nothing wrong with that) and they do not follow Guru devotion or encourage others to do so. As I understand it, Guru Devotion is the number practice of all Vajrayana buddhist. Ironically, they "follow" the Dalai Lama. Wonder, if one day someone said something negative about the Dalai Lama, would they "leave" the Dalai Lama. Wonder if the Dalai is actually their Guru?
Well, if you leave the Guru, it creates the cause for one not to have a Guru in the future or to leave Gurus one after the other. Looks like that is the future for them. I pray for them. May they have Wisdom.
