Your theory that somehow Bangladeshis are "inferior people"-whatever that means reeks of supremely egoistical and fanatical attitude. To say the least such racist theories are quite dangerous and reflect a lack of wholesome education. Mutinies have happened in Britain and France, and Germany too - the other self proclaimed "superior people".
The way forward is to shed such silly notions of imaginary superiority (which incidentally lie breed the perception of injustice at the root of such mayhems and coups) and work instead towards removing injustices which exist in our own country.
