Many of the observations in the post are correct, but the conclusion is far from correct. I had seen lot many Maharastrian, tamils or telgus engaged in similar practices.
People leaving their beloved homes - I lived in Middle east where seems like 75% population is Malyalam. It doesn't mean Keralaites are worst breed. To think of it, in middle est may be 15% people are from Maharastra itself (mostly Mumbai). So going by the post's logic, Mumbai should be termed as one of the worst places in country.
To conclude all I say do not go as Northies do not have attiquetes or southies are better ones. bad fishes are everywhere. And the leaders like Raj Thakre are plain terrorists, who in any shane place will get prosecuted. However our illiterate immature audience obeys them and tries to justify foolish violence by one citizen of India against another poor citizen of republic of India
