1. WHEN JEWS came from israel india welcomed them and they fell into love with the country and contributed to the country and proudly told the world that india has never persecuted them .....!!!! an anathema for muslims
2. When Parsis came from iran running away from fanatic muslim hordes .... they called india their 'MAADRE WATAN"" beloved mother's land and spread out in the world .......
india has always welcomed people who have been driven out of their homes and bangladeshis, nepalis, tibetans , srilankans need no introduction .
So shut up CPI M and go and hang yourself instead of questioning on others right to exist other than your piddle pot called bengal .....
