Gabby Giffords has no place in this discussion, unless you think putting cross hairs over her district and asking supporters to "take her out" is on par with calling someone a "slut". I don't think it is. So lets stick to the topic at hand, ok?
Beyond that, I think you've grasped my opinion. My opinion is that yes, someone who lives in the public eye is free to be made fun of and insulted, and someone who does not live in the public eye does not. This is in no way hypocritical as I apply this standard to many situations. Just because you don't like it, doesn't make it hypocritical.
I believe private citizens deserve the right to privacy. We disagree. It happens.
