I'm sorry, but what does that have to do with the price of tea in China? You think that's an example of "the left" disliking the military? Do you not recall what the "right" said about Kerry?
1) Just because you don't like it doesn't mean it isn't applicable.
2) "the right" didn't smear Kerry enmass. Many on "the right", including myself, disagreed with Swiftboat tactics. Don't forget, "the right", meaning the same small group of assholes, also smeared McCain.
3) Another example:
The Democrats' anti-war dilemma
“Democratic leaders must make a choice today: Either embrace the character assassination tactics MoveOn.org has leveled against the four-star general leading our troops in the fight against Al Qaeda, or denounce it as disgraceful”.
Like the Kerry smear, not all on the Left are anti-military, but the group of anti-military on the Left is far larger than the Swiftboat assholes on the Right.
