Donald Trump and his Muslim exclusion comment: Why this fuss?

A look at the world of politics, statecraft, diplomavy and Books Donald Trump, the Republican Presidential candidate, seems to have outrage the liberal public opinion with his comment that people from Muslim countries should be barred from entering the USA until America leadership figure out "what the hell is happening". This comment during the course of an election rally ought not to have created such a huge international controversy. What he says for getting votes from his constituents is of concern only to the US citizens, I am commenting on this statement only to expose the hypocrisy of his opponents. USA has practiced racially profiled exclusion ever since the establishment of the first settlements in New England. There was racially sanctioned slavery for over 300 years and even the Civil War was fought not to liberate the slaves but to defend the Union and the abolition of slavery as a war aim was proclaimed only as a strategic move in order to make the plantation workers/slaves rise in revolt. Generations of White historians have interpreted American History keeping the ideological objectives of USA in mind. During the COld War period USA was the leader of the "free world" as though the rest of the world was "unfree".Now the rhetoric of social inclusion is dominant and yet no one seems concerned that USA follows a policy of excluding the Spanish speaking Mexican from their territories and except for cheap labour the Spanish speaking people are not valued for anything else. No outrage over the proposed legislation which would identify illegal immigrants and repatriate them back to their home countries, breaking up families exactly like the slave laws once did. My purpose is not to suggest that USA IS SOME KIND OF A DEMON. It is only to put some perspective on Trump's remarks. USA has a system in which the Federal Government is the only empowered agency to regulate entry into the US and the adherence to International Law is questionable. We need only to recollect the instances of the "extra ordinary rendition", the attempted assassination of foreign leaders, the trumped up charges against Saddam Hussein and armed intervention in Libya are only some of the more egregious examples of US banditry. To top all this USA had the gall to put our Hon'ble Prime Minster on the exclusion list and ever one kept quiet. What Donald Trump has said comes from the same mind set that led to all the instances I have cited above. Historically too USA has imprisoned its own population in concentration camps on mere suspicion during World War II and still no reparations have been given to the interned population of Hawaii and California. It is sheer madness to condemn Donald Trump. If he is elected he has everyright to exclude whole populations on the grounds of national security and USA has been following this policy.
