It could be that people in Myanmar are so terrified of Islamist insurgents there that they have decided to rid their country of all Islamic religion and Islamic people.
For years prior there were reports that some Islamic people were killing Buddhists in their sleep. Later there was an effort to establish an Islamic province. Then Daesh started using horrific terrorism around the planet.
Now "suddenly" Myanmar is forcing out all Islamic people out of fear for their country.
All this is due to the fear instilled by Daesh.
Daesh has indirectly caused problems for all Muslims.
