There cannot be an overnight change but I believe the change is happening.
Millions of Indians have criticised this in the past and continue to do so. To deny casteism in India is like denying racism in the USA. The systems/power structure has not changed. The same old rotten filth continues to decide our lives and sorry we are not privileged enough to be free from caste oppression if we hang out with upper caste friends.
That temple incident is certainly bad and many social evils still persist in the society. The only way to quickly get rid of them is to have a China style 'cultural revolution', which involves destroying temples and other religious sites. But I guess it's not something which will go well with any Indian.
As far as the tokenism goes, keep in mind that the current PM is from an OBC. So much for the 'lower human' theory.

The above list is a sparsely updated list of caste crimes in India. What do you mean casteism is outdated? A dalit and a brahmin are equal in this society?
If so kindly show us a place where its the case!
