We have to face the facts about the role of Buddhist nationalists in the genocide of Rohingya Muslims. Most of us don’t know the denominations within Buddhism but it doesn’t really matter because the conflict is not rooted in religious differences so much as the manipulations of ethnic groups under British colonialism & the failure of Burma to address self-determination for its many ethnic groups when it gained independence. It remains a prison house of nations with Burmese Buddhists running roughshod in the manner of all supremacists.
The treacherous role of Buddhists in Arakan state is not an indictment of all of Buddhism. Buddhists have always played a role in the antiwar movement going back to the Vietnam War & of course within Vietnam itself. What’s going on in Arakan state is an aberration, not the norm among Buddhists.
