These bihari's has identity crisis. They were always Pakistan(country) supporter,never excepted bangladesh(country) as a country. After war Pakistan denied them to enter the then west pakistan. But still they think themselves as Pakistani though court give them Bangladeshi nationality few years back for humanity but still they don't consider themselves as Bangladeshi and these people always create dilemma to foreigners by using pak flags everywhere.That's why our gov't had to be hard on these type of people for not honoring the flag and flag rules.
