As Buddhist we are supposed to develop compassion towards other mentally and physically, what was said in the group has no such qualities of compassion at all.
The fact that people cannot have a proper discussion on dorje Shugden shows that people are relying on the the Dalai Lama like a GOD and they probably do not have the answers to many questions thrown to them. This reminds me of the 18 headed monster during Buddha's time who under the ill advise of his mother created a lot of suffering for himself. he was a brahmin who debated with monks from a previous buddha's time, and though he was the monks had superior knowledge and training, out of blind love for his mother he challenged the monks all the time. But he kept losing in debate, in the end, his mother advised him to use name calling (calling monks all sorts of animals) and rough words hence he was born as a beast with 18 animal heads.
I also liked what Kris said, Dorje Shugden practitioners do no commit the 5 heinous crimes that can be purified, there is no need or necessary to treat us badly.
