These spies have organized mandate, they work like soldiers, are well-trained. If these spies grow in number in a civilized nation, it'll be another worst happening for this country. Let us not forget how their masters rule, say Tiananmen Square, Tibet, look at the action of the spies at Nandigram, Singur, Taslima issue etc, the whole state of WB suffer from power cut (think if at all they come to power at the center, can you rule out the possibility of powercut countrywide?). Also let us not forget the stand of Karat and Yechuri on behalf of their masters in Nuclear issue. The states they rule are practically begging states. Compare Kolkata with Ahmedabad, Bangalore, Pune etc leave alone Delhi or Mumbai. Let us not forget the contribution of militant CITU unionism in our industries. If you accept them, start learning the Chinese language as that'll be language of this nation if they can manage to come (of course by scientific rigging) .
