I care about it because by not saying something explicitly it is not being made accessible to discussion. You might imply something that could be viewed critically, but by not explicitly saying so you dodge being made accountable for it.
I am NOT saying that this is what Damien did here. But I have a problem with this kind of response in general because of what I explained above. If you want to make a point, have the balls to say it directly or don't bring it up at all.
