I understand the sentiment behind the comment
What do you want us to explain that isn't answered by a simple web search?
but I feel it's not a comment that needs to be typed in this SE site. It is something one can probably find in some of the higher volume and more presumed-thick-skinned and angsty sites (e.g. SO) even though it's not nice, but here I think it has no place.
There is something insidious about the use of "us" in this way. It presumes to put the recipient in the position of not one of us and it simultaneously presumes to speak for all of "us". I feel this kind of language taints the site.
The reason "us" is used is because "What do you want me to explain..." sounds silly, and it sounds silly because obviously the answer is "nothing you don't want to explain of course!" And the fact that that sounds as silly as it does is the first hint that the whole concept of this question is ill-fit as a stackexchange comment.
I'm looking for a more standard, accepted, well up voted answer, perhaps in another meta where the "us" vs "you" angle taken toward a new user is dissected and discredited in a better way than I was able to do below.
I will do "a simple web search" after I've finished typing, and if I find an answer I like I'll post it. But this is meta and I've asked here because usually better viewpoints than mine exist out there and they are worth reading.
