Also, several families in SE Bangladesh this past Spring were forced to flee their homes -- also at the hands of Buddhists.
Here is an excerpt from that article: In the past year, an estimated 27,000 members of the predominantly Christian Karen tribe were driven from their homes in eastern Burma. In Koh Kyi village, in Arakan State, a monk backed by the military burnt down the local church. In another state, 300 monks were allegedly sent by the regime to forcibly convert the populace, all of whom belonged to the Chin ethnic group, which is mostly Christian. The document, shown to The Sunday Telegraph by human rights groups, may have been produced by a state-sponsored Buddhist group, but with the tacit approval of the military junta. The regime has denied authorship of the document which also calls for teenagers to be prevented from wearing Western clothes but has made no public attempt to refute or repudiate its contents.
