Absolutely not. Look at these numbers:
Religion in Burma - Wikipedia, the free encyclopedia
These are not inclusive of the Rohingya. 4% of the population (not including Rohingya) is Muslim and likewise 4% are Christians. There are mosques in practically every major town in Myanmar along with chirches. This is not a religious issue. This is an issue of the Rohingya; for whatever reason (mainly their desire to cede from the union and establish a caliphate), they are not wanted in Myanmar. It was very ballsy of Thein Sein to come out and say this and more importantly, I don't think he would have said it unless the international community tacitly agrees with his sentiments. If Bangladeshis truly care about their brethren, both in the 'ummah' sense and in the sense that they are essentially Bangladeshis, they should put aside their defiance and allow these people, those who want to, settle back in Bangladesh.
