Background
Both Myanmar and India have numerous ethnic groups within their societies. India has countless numbers of ethnic groups within their society, and they manage to have a stable democracy. While yes, there is discrimination between different groups, it has not resulted in a total government break down and seizure by the military, or genocide.
Myanmar, on the other hand, has much less ethic diversity, yet seems to be intolerant toward several ethnic groups, especially the Rohingya. Both India and Burma were under British rule as one colony and were exposed to the systems they set up there...yet India did not have a sustained military coup(s) that Myanmar had and currently has, nor did they carry out genocide like Myanmar did. The numerous similarities and proximity of India and Myanmar led me to ask...
Question
Why is Myanmar less democratically stable and more ethnically intolerant than India?
