I've been to many areas of Malaysia. From the middle of Bukit Bintang to the outback areas of Kedah. Don't try to lecture me on what I do and don't know about the country. There is a reason why the locals stay away from particular areas and behave the way they do. What makes you think you know more than a local? Because you have seen the 'culture' of the area? How pretentious.
And your pretence that you somehow know more than the people who live there everyday is not prejudicial? You most likely won't be robbed or killed in Malaysia. But it pays to be wary and to avoid the wrong areas - which are, incidentally enough, the poor areas. No different from any country.
So there's really nothign to point out then ?
