Myanmar had an infant democracy. You can't expect it to be an adult overnight and killing it abruptly is not a solution.
Myanmar is mostly composed of Bamars with clear majority while 100s of other minorities are fighting for recognition. This coup had made them come together to fight against the military rule. I just hope the transition back to democracy would be peaceful one.
It is not a Bamar vs minority fight in Myanmar. Both the Tatmadaw (army) and the NLD are dominated by the Bamar ethnic group (68% of the population). And when you talk about the minorities, they are not a homogenous group. There are 134 recognized ethnic minorities. The largest ethnic minority is the Tai-Shan group, who constitute around 10% of the population. Culturally and religiously, they are very similar to the Bamar. The third largest minority is Karen (7%), who are divided into majority Buddhist and minority Christian factions. The next largest groups are Buddhist Rakhine and ethnic Chinese, who constitute around 3% to 4% each.
Among the minorities, there are groups that are supportive of the army (Shan, Mon, Buddhist Karen.etc). Then there are non-Buddhist groups such as Rohingya, Kachin, Chin and Baptist Karen who have been fighting the army for many decades now. There is a third group, which is comprised of ethnic groups that are controlled by the Chinese government (Wa, Palaung, Kokang, Lahu.etc). These groups control their own territory, and use Chinese Yuan rather than Kyat as the currency in their areas. They are supported by the PLA.
Now a fourth faction has emerged, with the Buddhist Rakhines rebelling against the central government. They used to be pro-army earlier. But now they want more autonomy and are clashing with the Bamar dominated authorities. And finally there are Indians and Nepalis, who comprise around 2% of the population. This marginalized group doesn't have any political power and are being assimilated into the Bamar community.
