6. Lakshadweep and other islands
The six states listed above are as unique as The united states of America and India. Every state has its own unique identity. If we go on based on the linguistic basis(The methodology used for framing states) we can list the languages in the same order
4. Telugu(A little difference in pronounciation)
5. Tamil, Malayalam, Telugu, French(Yes)
6. Malayalam, Mahl
Now, I dont see how all these different languages which are so different can be compressed to one single language called Tamil. A person proficient in any one language will not be able to understand an iota of any other languages. The way the languages are written dont match. They are ages different from each other in pronounciation and written words. Each language in its uniqueness speaks volumes about the differences in culture, attitude, outlook, practises, Ideals and other human properties.
In fact, in Karnataka, there are other districts which speak completely different languages and are fighting for a "state" status since they have their own original language like Tulu and konkani.
But, when it comes to Bangalore, things change. It is the one "real" cosmopolitan of India. Uh uh, Ok. What is the purpose of this post? The purpose is not Jingoism, the purpose is information, the purpose is clarity. So, anybody visiting souther india, Just remember you are visiting a world altogether. It is not visiting all the temples in south india in one go. It is understanding the uniqueness of all the groups of people. Nothern India is very careful in differentiating itself as Marathis, Gujarathis and etc. We dont believe in that. We are unique but we are a part of the family called the "World". But if you want to identify us, do so with each of our uniqueness.
I want the mass media and the film industry to please do some home work and put some work into selling the uniqueness of all the souther states with the district you are thinking of also. Give all the southerners our own identity. Dont you make a stamp and press it on us.
