Peaceful Buddhists?

The Rohingya Muslims in Myanmar (Burma) are being horribly persecuted. The Tamil Hindus in Sri-Lanka have been horribly suppressed. The ordinary people of Cambodia were horribly massacred. Each of these things has happened in a country with a Buddhist majority (though of course the oppressors in Cambodia were acting in the name of Communism). I have no doubt that good Buddhists are peaceful people, as are good Christians, good Muslims and good Hindus. But a lot of bad things are done by people who imagine that they are good followers of their respective religions. Religious labels don't mean very much.
