But then, what is the point?
This is where it gets tricky, admittedly. I have a hard time buying into the notion that we are fighting for *our* freedoms. We're not literally defending our country... though maybe we are, in a round-about sense. Personally, I believe we should pull out immediately and completely, but for different reasons this this issue.
Be that as it may, freedom of speech and expression is not conditional or situational. You either have it or you don't. You either defend it or you don't. Sometimes it will be inconvenient and less-than-satisfying. That's how flag burning (in our own country) is to me. (I don't give a rat's arse if someone in another country burns our flag.) I detest the thought, but would defend the right of others to do so. It's not just about me, or even the individual defending said freedoms, it's about the whole thing as a concept.
We won't like the where the road leads if we start cherry-picking which speech is acceptable and which is not, no matter how we justify or rationalize it. Essentially, we defend the actions of those which are abhorrent to us so that, when it's our turn to protest, we can do so as well.
