Its not the Congress that was responsible for the Muslims who thrived in our country. Rather, its the common Indian, who in his culture, has a (mostly) open mind, and wishes to live peacefully with his neighbours.
I'm sure Sania or Mr.Premji would attest to this. They dont feel alienated in this country because that's simply not in the culture of the vast majority of Indians.
The Congress party has done the usual buffoonery it does to garner votes of less-informed people.
