Whole world sympathize with Rohingas not because their religion but because they are human first. Genocide against anyone is a crime. And using force to displace ethnic minority is ethnic cleansing. I suppose you have not learned basic human values.
In Bangladesh there are large number of Rakhine Buddhists who has ethnic root in Myanmar Rankine province. Bangladeshis did not raise a hand against them even in the face of provocation from Myanmar. Nor Bangladeshis demanded Myanmar should take Rakhine people back. That is how human should behave. NOT like some Chinese suggestion of ethnic cleansing.
