Why can't I down vote the concern troll? Or, why aren't those with the power to down vote able to detect the concern troll? A valid argument was made that couchsurfing.com is an actual sharing economy and AirBnB has stopped being one. The concern troll ignored and derailed the argument.
This comment is much more useful than your grandparent comment. Down voting might be the correct action (if you were able to), but a short meme/snark comment is almost never appreciated.
For what it's worth, I actually agree with your point. The parent of your first comment was (at least to some degree) derailing the conversation. I didn't even consider that it was a derailment until your second comment.
I think you did have something valuable to add to the discussion, but I did not initially see it because your first comment was so pointlessly unnecessary.
Based on you pointing out the behaviour, I will now try to recognise and downvote 'concern trolling' that derails conversations. It's unfortunate that you weren't able to communicate that more effectively the first time.
