I do thank the Nyingma Lamas and practitioners for their compassion and courage to tell the truth as it is. Not to give in to hearsay, but to employ all faculties to investigate the truth behind, one such luminary I believe is His Holiness Penor Rinpoche

I wouldnt want to judge that the Nyingmapas are against Gelug just because one or two of them say bad things about Dorje Shugden. One good example of a Nyingma Lama that has kindness and compassion is Penor Rinpoche. He showed compassion and kindness to Shar Ganden and Serpom even when they were denied by their own community. While some Nyingmas are really against Dorje Shugden and they kind of see Dorje Shugden as a destroyer of their lineage, there are also other Nyingma Lamas who are netural in this matter and who do not take sides.
