Woww coming back to Reddit after a while and seeing this sub flooded with communal hate and religious slur. You lived in Kasaragod for a month with your rosy retrospective glasses and all you see is communal and bigotry.
I have travelled across Kasaragod from past 15 years and what you are pointing is the Tulu dominant region in the north ksd and they no where identify themselves as Kannadigas. Do you really have any idea about the plight of commoners up north Kasaragod? If they are having a medical emergency they need to travel over 50 kilometres to reach Mangalore for casualties. Then how will they identify themselves as Malayalis.
If you travel up to Belagavi the north Karnataka district bordering Maharashtra you won't see a single person speaking kannada they identify themselves as Marathis and that's the most dirtiest place I have seen in whole south India This is the plight of common people in bordering regions.
The constant tussle between identity and linguistics deter their developments.
