Deadly Virus Becomes Political

The insidious Ebola virus, once restricted to a few countries on another far away continent, has stepped foot into the United States. One traveller from Liberia, came here asymptomatic on the flight, but revealed symptoms shortly afterward. Released from a Dallas hospital when he went there with a high fever, Thomas Duncan evidently was misdiagnosed and sent home with an antibiotic. After coming in contact with approximately 100 people since his arrival,  Duncan soon succumbed to the deadly virus. Many people are now claiming that it was due to racism that Duncan didn't get proper treatment. Jesse Jackson says it was due to his race and lack of privilege which kept him from receiving the proper care.

We've heard time and time again over the last couple of weeks, by CDC Director Tom Friedan, that banning flights from west African countries would not only not make a difference in stopping Ebola from coming in, but may make it worse. That sealing the borders would not help because it would be harder to get medical supplies and personnel in to fight it.  That isolating these countries would enable the virus to spread further over there, thereby making it tougher to get a handle on it. According to Anthony Fauci, head of another government agency, it would then cause those countries to panic and lead to unrest, possibly the fall of their governments.  So now the concern shifts to the governments of these African countries and away from the safety of the American citizens?

Here'a a little known fact about this administration - in 2010, after opposition by the ACLU and other groups, Obama very quietly scrapped proposals by the CDC to impose stricter regulations to detain sick travellers and to require more reporting from airlines to better track sick people. These new regulations were "critical" according to the Centers for Disease Control. Now the administration is silent on that decision, and naturally, so is the supportive liberal media.  According to Media Research Center (MRC) most TV networks won't even inquire as to whether the government is doing enough to stop the disease from coming in.

Anyone from the political Left, please explain. Our country, and the world, are facing the prospect of a pandemic from a deadly virus. Since we know from which countries the virus originates, the common sensical action would be first to ban flights from the Ebola stricken countries (notwithstanding the shipment of medical supplies and personnel). Banning passenger flights would be a good first step (despite what the government is trying to convince us of) and already a few European countries have done that. One liberal commentator even went so far as to suggest that we owe it to Liberia to keep travel open, since America, a few hundred years ago, imported slaves from there. How can we turn our backs on them now, he said? If this isn't completely warped, I don't know what is.

Secondly, close our borders. This seems too obvious to even mention, and yet, this administration refuses to do so. Why? And to add further injury, some are speculating that if Ebola enters into Central America, those citizens will be making their way into the United States, through our open borders, by the thousands, looking for treatment. The implications for keeping it under control then are frightening.

So, to those on the political Left: why is wanting to keep our own citizens safe, racist and incompassionate?  Above all, why is this political?
