Kamans are just like the Rakhines - they look quite the same. Rohingyas come from Bangladesh and are Bengalis so they look like the people from Bangladesh.
Anyway, Rakhines and Kamans have lived in the same land for centuries. They should have their rights, freedom and cultures. That should happen. The central government of Burma must allow them the way they are with best protection. Burma should change fast.
Rohingyas might be able to live in Burma for some reasons. Children who have Rakhine (or Kaman) father or mother should have the right to be in Burma.
