Dear Mr. Krishna, for centuries people in groups have been moving from one place to another. For example, today more Irish people are there in America than in Ireland. This does not mean there has been an onslaught by Ireland. With the advancement of technology, need to search for more fertile lands, prospecting for minerals etc. social groups have always been moving from one place to another. I am sorry but you can not keep yourself isolated for very long. The very fact that you have chosen to express yourself in English goes on to prove that you have also been trapped or is it that you do not have objection to suffer onslaught from the English.
