"I think a more interesting debate might be, which is a greater threat to America, terrorists or liberals?"
Good point, although how much difference is there between them; One lies and the other swears to it. Or, as in the Mafia, one gives the order and the other pulls the trigger.
But Michael Savage and - was it Cicero? - is right: the enemy within is far more dangerous than any external enemy; therefore the Liberals (Socialist, xenophilic, Tower of Babelers) are the worse danger of the two. They have their slimy hands on the levers of our government.
Here you go...
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murderer is less to fear." Marcus Tullius Cicero - Roman Statesman - Speech in the Roman Senate - 42 B.C.
