Defensively, not pro-actively. I can see lib/dems I know throwing this in my face. Why not have a little ammunition?
Uh, because it's disgusting and repulsive and indecent and grossly disrespectful to those who are already dead and those who will die in the next few days? Is that a good enough reason?
If you want ammunition to deal with the lib/dems who are throwing it in your face, try this: "I'm revolted that you would even think of politicizing this tragedy while the bodies aren't even cold yet. If you want to talk about whose fault this is, I will be happy to oblige you... later." That's all the response such a slimeball deserves. Anything more makes you a slimeball just like them.
