My attention has been drawn to an interview of Jacques P. Leider in the Irrawaddy.org. Here is my comment below:
Jacques Leider is long known for his academic dishonesty. In his own writings he mentioned that during the British era only a few dozens of Bengali migrants moved to Arakan, and now he claims that Rohingyas were not known until the 18th century. Well how about poet Syed Alaol's writings from the early 17th century?
