I was very young when I saw (and still remember) Congress party goons setting fire to Sikh homes in New Delhi. I heard stories of how congress party workers in Delhi butchered countless Sikhs. Please note that I am not defending Modi in any way and I despise right wing fascism everywhere.
There are few redeeming things about Congress rule, but to call it very well run government is an exaggeration.

I also dislike that we have to constantly add "we are not defending modi". It comes from their belief that the only ones who criticize Congress are hindutva nationalists bigots. As if congress did nothing to receive the ire of the people.
