I have been having discussion with various people about Marathi and MNS and what Raj Thakre has been saying about it.
I think one very simple solution for this problem is to expect that cultural diversity in India is there to stay and it should be expected for everyone to learn local language. But it can not be enforced in the use.
Teaching Marathi to more then 60% of population is not easy, but it is not an impossible task. It can be done. But what MNS and Raj Thakre should understand that once people learn Marathi, they are going to stay, they are not going to go back.
