Absolutely possible that's there's an equal number of migrants from other states as well. However, if a third language is to be put there, and say Hindi is chosen as the third language - just to cater to another language speaking community, I don't see any issue with it. Again, absolutely fine to replace Hindi with Telugu/Tamil/Malayalam, but that didn't happen. They just scraped off Hindi, so it was clear that there was never an intention to put a third language out there.
Also, I understand why you ended by stating that you don't support the hooliganism. It's very sad to see how we have to defend our take AND add additional statements to assert political correctness. I hope we as a society get better and allow people to express freely without them being scared of words taken out of context :)
