I'm arguing that the statement does no such thing. It was pointing out that Kirk said a number of gun deaths was a price worth paying. I think most people would accept that the phrase "price worth paying" indicates support for a position even if you stick in a gratuitous "unfortunately" to make your position somehow more palatable.
I don't support murder, and neither did the statement. It pointed out that the writer did not believe that gun deaths were necessary, whereas CK did.
This appears to be an argument about semantics more than anything else.
Your comment about language being important is true, perhaps that should have been taken up with the now, apparently venerated Mr Kirk when he was spewing hate every which way. Words do have consequences, even if I don't like those consequences.
EDIT: I probably won't respond further as it appears we are reading the statement in fundamentally different ways, I apparently can no more see your pov than you can mine.
