The left is free to do and think whatever they like, unlike the ideologues on the right, who all fall in line behind whatever corporate and conservative think tank and media are telling them to repeat. Note how many apologies the republican presidential candidates give every time they have an individual thought or engage a talking point that is sacrosanct. Freedom for the right is slogan, marching in line behind the ideological lines is their only refuge. The question on taxes at the debate exemplifies the right's lack of free thought. And their booing a gay soldier nailed them. Of course the left suffers politically because of their inclusion of all people and all ideas, but that at least is more American and democratic than the lemmings on the right.
LOL, it's not our fault the left doesn't have ANY CORE princibles and you all run around in circles tring to figure out what you all believe in. Just look at the Wall Street protesters, just WHO is marching in line or I should say, BEING LED BY THE NOSE.
No one is asking you to, America was founded on diversity and tolerance of all ideas, an open idea you can call it core if you like but it doesn't fit your ideology. And do you think Enron, Arthur Anderson, and all the corruption that lead to the near collapse of the economy in 2008 under a republican was just wonderful? Seems you are so brainwashed you fail to see reality. Protest is American, whining about freedom and justice for all is right wing conservative republican.
