Rajeev, please do not react to a single situation. This arrested person happened to be from 'Kerala'. Hence, it is easy to say Mallus go back.
What if someone from Karnataka gets arrested in Kerala? Won't they scream: Kannadigas go back?
I mean, how much more longer we have to live like this? We should be proud of local, regional culture. But at the same time, we should also look at "Mother India" as our Motherland.
Till we don't do that, I feel we will continue to be exploited like this by our enemies and we will bicker amongst ourselves forever.
