well it mainly depends where you are brought up....i have seen from my experience that most of the bangladeshis who have migrated here at early age did pick up american sports but those of us like me who have come here late, cant seem to forcefully like american sports....it has to come from heart....naturally...
in fact, the opposite could also be asked: Why do the Bangladeshi-Americans like baseball and dislike cricket so much? Is it because they think it will make them lesser of a 'g' or 'uncool' to do so?.....dunno
