Well stop agonizing about it and delete it then. I'm not saying that to be snarky, I'm pointing out that it's something useful you can do right now to get it off the top of the page.
That doesn't accomplish anything useful. A day or two from now, someone who hasn't yet seen the thread will wonder what the "deleted" part of the conversation was for.
The best thing to do if you disagree with the position of the OP's comment is to upvote other siblings. Personally, I think this discussion is interesting because it addresses in real time the implications of what this attack might be (if any).
