Your logic is, Since Bangladesh was restored to be secular by the 2010 Bangladesh Supreme court order, hence it will be (
the ONLY??) livable place for everyone to live equally.
By that logic, since India has been Secular(Constitutionally) since 1947, everyone has been living there equally since 1947 at least.
If you're alluding that some BJP and RSS are communal & some of their people are creating disturbances based on religion, Bangladesh has had communal incidents as recent as 2013 when BAL was in power. Also, since Bangladesh is a democracy BNP(the party on the right) will also come back to power in the future, hence we might possibly see similar communal incidents.
However, now because Bangladesh is secular and does not have draconian laws for blasphemy and apostasy, the minority Bangladeshi citizens(including atheists) have protection & should not have much to fear
from the Bangladesh government.
I congratulate Bangladesh for it's progressive constitution and laws!, which are largely catching up since 2010 with Indian laws existing since 1947.
[Btw, Islam is still a state religion of Bangladesh, not sure what that means though]
