Pentagon's Iron Curtain uses Blue Coat software to censor Democratic and gay sites, while allowing access to GOP, right wing, hate group and antigay sites

Giant message plowed into field in front of Offutt Air
Force Base outside Omaha by Chris Shotton and paid for
by a Walmart Supercenter in neighboring Bellevue. The
US Air Force is engaged in large-scale, unconstitutionally
partisan Internet censorship affecting servicemembers

UPDATE: The Pentagon says it's looking into the issues raised by AmeriBlog.
     John Aravosis at Ameriblog has discovered that the Pentagon (especially the US Air Force, if the screencaps are any indication) is still engaged in large-scale (but piecemeal) blackouts of gay and liberal websites. Complaints documenting this practice are at least six months old but haven't been addressed, evidently. Some samples provided by Aravosis' research:

Blue Coat Internet-blocking software, purchased by the DoD,
has a special, preprogrammed "LGBT" category. Aravosis
notes that Blue Coat does not offer "Latino," "Jewish,"
or "African-American" categories.
