I am glad that BJP has faced a very embarrassing defeat. This clearly shows that the people of India are Sick and Tired of BJP's Hindutva stance. I am personally not interested in having such Sick parties with their Sick ideologies run the nation. I serioulsy cant figure it out as to how these parties claim to be protectors of Hinduism. I am sure 99% of the people who work for BJP have not gone through the Bhagavad Gita even once in their lifetime & these cheapo's call themselves our protectors. This is to remind all the people who support BJP's ideologies.
So learn to leave in Peace with everyone. I hope BJP now changes its attitude after this embarrassing defeat. They should realise that unlike Monkey's they have in their party and also those who follow their sick communal ideologies, the whole general public is not.
