Then why did Buddhist Burma sack the capital of Buddhist Siam in 1767?
Don't forget Buddhism is a major influence in Japan which is not know for its pacifism and today the Buddihist majority is fighting the Hindu minority in Sri Lanka.
Even Tibet fought wars.
Can't use Japan as an example Tribune. They use Buddhism very selectively. Shinto traditions also play a very powerful role and it was those traditions that drove their imperial ambitions.
I'll research your first point and get back.
Don't agree with your example of Tibet - Tibet fought wars against the Chinese when they were still relatively underdeveloped and like the Mongols, raided the Chinese for quick wealth. Once they accepted Buddhism, they essentially became a peaceful lot.
Also don't accept your Tamil/Sinhalese example in Sri Lanka. That conflict is based on language (Sinhalese versus Tamil), race (Sinhala versus Dravidian), and ethnic origin (ethnic Sri Lankan versus Tamil laborers brought by the British). Religion has almost no role in it.
Even if you were right about your examples, which you are not, they is still a far cry from the atrocities commited under the name of Islam and Christianity.
