2016 Postmortem

For one, "concern trolls" are like voting fraudsters. There is way more CONCERN about stopping 'concern trolls' than warrants the amount of them that ever slip through. You are so CONCERNED with an influx of concern trolls that you had to make an OP on it?
The irony.

And I also think you don't even understand the purpose of a concern troll.
A good definition I found:
https://www.urbandictionary.com/define.php?term=concern%20troll

In an argument (usually a political debate), a concern troll is someone who is on one side of the discussion, but pretends to be a supporter of the other side with "concerns". The idea behind this is that your opponents will take your arguments more seriously if they think you're an ally.

A concern troll would not work in this instance, on DU. Why would they even try? No one on here is going to be scared into voting for Trump because someone said they are worried about, say, Hillary's emails.
Concerned about silent Trump supporters, or just reality TV fans that don't usually vote, answer polling calls, or even follow politics much deciding at the last minute it would be 'something different' or 'entertaining' to have Trump in charge, and worrying that some on our side will get complacent with Hillary's poll numbers IS NOT CONCERN TROLLING! It is keeping people awake and wary of complacency. Personally IMO, DU is already theoreticllly at least, 100% voting for a Democrat anyways, so I'll grant that complacency is more of a problem with those luke warm Democrat voters that don't have the interest in politics enough to join a message board. So those concerned it is more about venting about their worst fears for events OUTSIDE of DU. It is harmless though, and no need to be so damn CONCERNED about it. That does more damage, causes more antagonism in here and for nothing.

Some people are simply more sensitive and anxious than others. Its just in their nature. In fact every group needs these to balance the over the top hubris of those that never see danger and assumes the majority is always on their side. Did you ever consider that these 'trolls' are just the more sensitive segment of DU, and are ALLIES that you maybe shouldn't be laughing at and ridiculing?

Its also a cowardly thing to do. Easy to spout out how anyone that thinks Hillary, (and YOU by extension) is still in danger of losing is a TROLL. But of course no one would even have the stomach to tell you they told you so if the worst happens.

Poll before the Brexit vote:



I wonder if there was some poster on a British liberal leaning message board before that vote that was 'concerned' about a hidden surge of ignorant voters, and if they were also ridiculed, and/or banned for raising their concerns at the time.
