Any pro-#Rohingya groups hesitating to condemn the statements of Ata Ullah and the Arakan Rohingya Salvation Army need to consider the long term consequences of being associated in any way with this group and their rhetoric; even the perception of an association.
For example, humanitarian aid groups can easily be accused of providing material assistance to the insurgents, which will collapse any efforts to get assistance to the needy, and to even collect donations at all. Donors themselves may find themselves subject to prosecution.
Indeed, getting financial support for any Rohingya assistance programs will become risky.
If the rebels are classified as a terrorist organisation (which is probably just a matter of time), the ramifications will be enormous and devastating.
Any aid, any support for the Rohingya is going to become next to impossible.
