These far left protesters, of course, are not really "anti-war." Rather, they objectively and implicitly support victory by the Islamic fascist enemy.
Also, liberal and Democratic Party protestations to the contrary ("of course we support our troops - we just oppose their mission"), these so-called "anti-war" activists don't "support the troops."
Disruption of our troops' mission directly endangers their lives, and (if successful) would literally aid our enemies.
From my own 1960s and 1970s experience as a leftist antiwar protester, I know from the inside how radical extremist elements manipulated the so-called "Vietnam peace movement," objectively aiding the communist enemy and helping increase the possibility of communist victory. That communist victory, in turn, led to the massacre of millions and to vast related human tragedy.
Today's "anti-war" radicals, like those of the 1960s and 1970s, bristle at any statement regarding their lack of patriotism. But the far left elements manipulating anti-war sentiment are far from patriotic - many of them consciously and deliberately oppose the very concept of patriotism.
