Indeed Nehru (first govt head of free India) put the foundations of scientific thinking in India. Built great institutions and foundations of IIT, BARC. But India capitulated it's advance to religion and tribal mentality.
Funny enough even today people like religion based leaders and chosen a government whose head proclaims in a science conference that before England invaded, India invented atomic bomb, aeroplane during ancient time of Lord Ram (a deity) and invitro fertilization during Mahabharata (religious book). India really needs a science revolution who can throw such leaders out and chose at least an educated one who understands science, that's the only way to bring up scientific temperament and progress. This will help avoid attacking neighbors or take religion driven populist changes to divert attention from real issues.
I understand racism in Indian context means untouchables, social class hierarchy, killing a person for transporting cows or marrying out of prescribed social order. I am not talking about it.
