There are regional tendencies in India. For long there were separatist movements in Assam, Punjab, Kashmir, Nagaland, Manipur, and Mizoram. Some are under control but not over. Tamil Nadu there were attacks on pilgrims from Sri Lanka. Some talk of Maharashtra for Marathi people. Uddhav Thackeray spoke of permits for Biharis. Digvijay Singh said Thackerays were originally from Bihar. He said Uddhavâ€™s grandfather Prabhodankar had written in his book Mazhi Jeevangatha (My life story) that Thackerays were from Magadha in Bihar. Uddhav said Prabhodankar referred to Thackeray community and not to his family. Even if Prabhodankar did not migrate from Bihar some ancestor of Uddhav migrated from Bihar.
Manohar Parrikar said Goa is for Goans. Goans outside Goa are many times the number of Goans in Goa. Over the centuries Goans have migrated to many cities in India and to many countries. UK MP Keith Vaz is a Goan. Rajdeep Sardesai of CNN-IBN is a Goan. Lata Mangeshkar and Asha Bhosle are Goans. Goa is smaller than many districts of other states of India. It is smaller than Coorg in Karnataka.
Many tourists visit Goa. If tourists stop visiting Goa many Goans will be unemployed and have to took for jobs elsewhere.
If every state in India asks Goans to leave, Goa will have a big problem.
