I agree with Dr Ananthamurthy that people who have migrated to Karnataka should voluntarily learn Kannada. I am a migrant myself, but would never shy away from this obligation under the hollow pretext that anyone can settle anywhere in a democracy. One acquaintance of mine - a Tamilian by origin and now settled in Bangalore - said this about Kannadigas: If you walk one step (by trying to learn Kannada), they will walk 10 steps to be friendly with you. I am willing to believe him.
