Let's assume that's the case (although it's a strange custom because, again, it's quite conceivable someone comments something that in itself is newsworthy and comment-on-able).

If it's impolite, presumably the magical social filter will take care of it by downvoting or ignoring. Calling in the heavy artillery for something trivial like that is still ham-handed and unwarranted. You can't have said something like that unaware that it will end up all over the place anyway, as it did.

The thread was flagged and removed before PG got to it. So yes, it was voted against social mores.

It was voted because you asked people to flag it

Sure. But they did it.
