I can understand your fear. If I step into your shoes I will feel the same way as you are feeling. Insecure. This insecurity is arising because of demographic changes that are talking place in the world. As a hindu one would be disturbed to see his/her religion losing importance in the daily lives of people. Apart from that there is loss of land mass that is still going on in the eastern parts of india. Your fears are not unfounded but you have to realize that strength of community does not come from outside or from the abuse of the outside world. It has to come from within. I dont think I will convert to any other religion even if I am forced to eat pork three times a day.
