Which land & what brotherhood you are talking about! Considering your ideology, would you give Kashmir to Pakistan just because majority of population is muslim. Extremists & Radicals are misguiding the muslim population in Kashmir & here in Belgaum MES is misguiding marathi speaking people who are least interested about merging with Maharastra. You are just talking about Belgaum & do you know the consequences of the country if remapped based on your ideology. Our neighbouring countries are jealous of our unity & people like you are trying to divide the country. I have been to Belgaum & also adjacent areas several times & my experience is that both Kannada & Marathi people are living in perfect harmony. As you said still 25% (I hope it should be more) of Maharastra is still backward why only interested in Belgaum & why not those backward areas. So what you know many languages & lived in many parts of India, your thinking is not broad.
