As a longtime member of the Democrat Party (since Reconstruction), I've been very concerned this election cycle.  I plan to vote for the Democrat nominee (whoever they may be) but feel the need to detail my many concerns.

So there are folks who don't know, or pretend not to know, what concern-trolling is.  I thought I'd help everyone out by using Teh Google to provide everyone with an easy definition.  

From wikipedia:

A concern troll is a false flag pseudonym created by a user whose point of view is opposed to the one that the user's sockpuppet claims to hold. The concern troll posts in web forums devoted to its declared point of view and attempts to sway the group's actions or opinions while claiming to share their goals, but with professed "concerns". The goal is to sow fear, uncertainty and doubt within the group.

It's pretty clear that quite a few comments (and diaries) are written here with the intent of "sow[ing] fear, uncertainty and doubt".

Concern trolls aren't doctors or lawyers or magicians or ditch diggers or ducks.  Concern trolls are concern trolls and should be called out for their bad behavior.
