It's a fair and honest criticism that has produced interesting conversation. You're being mean-spirited as well, but you think you're exempt. Shove off.
What does add to the conversation, apparently, is continual snide assertions that parent didn't add to the conversation.
(I actually don't have any problem with snide obnoxiousness. "I'm amazed you could [be so incredibly idiotic]" is upfront at least. What I do get tired of is a continual tree, like this one, of "You shouldn't have said that.")
It's funny to imagine anything like Reddit's (?|?) controversy here.
