Regarding ur baseless comment on south India , see the following situation and say what can I say about north Indians....
Once...
more... because of a bunch of north Indians , I have lost my friend in train accident. He had reserved in sleeper class in prayagraj express, he went to rest room to vomit as he felt nausea. Few north Indians were sitting in bathroom and did not allow him inside saying him to vomit near the door , so he went near the door , he lost his balance and injured his severely and lost his life. If I go by your logic even I can say north Indian peoples are so arrogant and uncultured but I did not say that , since its not good to term everyone like that just because a bunch of idiots behaved like that.
