A simple question for you....
During the 2012 series of hartals (when the season just began), BD flags were burned inside BD in places which still support Pakistan (and dream of a United Pakistan). These same people had raised Pakistan flag. i had witnessed this in Noakhali, where I was personally present on a visit.
The same flag is being burned now (you might claim they are controlled by remote from India..I'm not judging you)
Why should it be an issue now? Your parliament made a statement on a Bangladeshi internal matter, it will have some consequences right(albeit minor)?
As far as the Pakistani embassy is concerned, they would be perfectly safe...its just a demonstration(usual stuff in BD)

On a side note there is no need to cite the Vienna Convention...it suits only USA as we speak
