Good blog etiquette would be to give a tip of the hat to Instapundit or whoever linked you to this. I suspect you don't read any liberal sites at all much less the Democratic Underground.
You do have to give them a slight pass because of the context. I'm not in any of these circlej*rk politics boards but I used to be pretty into a Buffy the Vampire Slayer discussion board, and I know that if you ask a question like "what do you like about Buffy" *within the group*, you will get a much different answer than if you ask them outside or at work. Instead of just saying, "Spike's cheekbones," you'll modulate your answer thinking, "Everyone's heard of the cheekbones, and half the people think anyone who still likes Spike is just a fangirl," so you'll say, "The fact that Angel hasn't tripped over his own trenchcoat in three episodes" or something that will make people think you're still interesting.
So in this case, you can't just say, "I love our freedom" like you would if you were talking to someone from overseas. You know half the people there will think you're blowing off their wiretapping concerns and are a closet Republican. So you engage in some public communication and modulate to "I love the freedoms we have left." Sounds like unnecessary, unpatriotic qualification to the ousider, but that's not who it's intended for.
That's answer A. Answer B is, "If Republicans questioned my heterosexuality as much as they question my patriotism, I'd start making love to goats. If patriotism makes you vote Republican, there must be something wrong with it." I seriously would call my own mother an off bitch if everybody kept telling me I had to say "I love you" or give aid and comfort to the enemy.
