The fore-fathers of the current generation of Muslims did not flee to Pakistan because of the respect of the homeland called: "India".
They voluntarily wanted to stay back here. So they did.
But our enemy is clever enough not to let this noble thought percolate to the present generation. Hence we are witnessing this deviation.
Also, during the 60's when the US abolished racial discrimination, it made sure that it is stringently implemented across the length and bredth of the country.
Even though our constitution does not differentiate between Hindus and Non-hindus.
It is only petty politicians who are trying to widen the gap in the minds of people which the British so successfully created when they fled our country.
We are also to blame here.... Do you think, the customs officials who ought to be checking the infiltration from across the border are NOT hindus? I am sure they are..... Aren't they "Gaddaars" then???
