How ironic! You are celebrating Wesak day, the most important Buddhist festival when the whole world is commemorating the birth, enlightenment, and death of the Buddha, yet what you are doing is in total contradiction to Lord Buddha's teachings. What is the point of celebrating Wesak then since you don't even want to listen to Buddha's advice? So hypocritical!
Exactly, they celebrate Wesak day with discrimination, anger, hatred and jealousy. I don't see how they can have a successful Wesak day with a lot of merits accumulated. Instead of accumulating merit, they will be collecting de-merit since they harbour negative emotions.
Buddhist are supposed to practice tolerance, kindness, compassion, harmony, and peace. Just because somebody has a different belief system, it does not mean that they are bad people and their belief system is evil. It means that they are just different.
If they condemn Dorje Shugden practitioners, do they condemn the Muslims and Christians too? Their belief system is different too but why aren't they are labelled as Devil when they are in the same setting. This is the dicrimination.
