Then you know absolutely ZILCH about Bangladeshis then, that is the honest trust. "All Bengalis are dark" but when they see a Bangladeshi and then in awe because this person cannot possibly be Bengali, that's the mentality I see most of the time. Most Paks seem to be very surprised when they see a Mongoloid Bengali but you just have to go NE Bangladesh or SE that you will see thousands of them and yes they are Bengali Muslim.
I've never heard an Arab say that to be honest, how ever I can say myself that I have seen Pakistanis look Arab, especially the Kashmiris. And to follow that, I've never seen any race so into skin color than Pakistanis and that's purely down to the attitude I have seen.
There are more important topics than finding out differences between ethnic groups. Everyone is out to make their bread and butter but I thought I'd clarify a few things. I hope
@Riyad who lives in a country which is 98% Bengali has now learnt a thing two.
