Blunders of congress and other parites are all well konwn to anyone with little bit of eyes and ears open, even though, Non-BJP et el have succeeded to bring rap to BJP only by their untiring criticism of BJP.
It's well-known Nehrus desire for PM was the immediate cause of partition of India. Personally, I think, partition was good. Due to lack of strategic vision on part of Nehru and Gandhi, the goals of partition were never acheived for India. We're still left with more than 50% muslim population staying put in India while Pakis succeeded in what they wanted.
Congress, led by Nehru clan continued with their flawed and psuedo secularism with thier eyes on biggest minority as their vote bank. They never-encouraged and blocked this minority's entrance to country's mainstream.
Then came the casteists led by VP Singh. They used this powerful tool of creating hatred among castes to steer their way to power. Casteists are biggest danger to this country. They use this historic divide in our society and thier goal is to strenghten it for thier own selfish interests.
Congress didn't mind going the casteists way as seen recently seen moves by Arjun Singh supported by this puppet PM and super PM. Congress is not only communal but also casteist.
I know, minorities are scared of BJP. They shouldn't be as BJP stands for equal right for them. I see BJP as the only hope for uniting the people of this country on basis of common thread of out heritage what they call Hinduvta.
