Concern trolling

Concern trolling is basically when you pretend to care about an issue in order to undermine and derail any measures that would be taken to address the actual, underlying problem that’s affecting society. Instead, it’s a tactic that’s used to:

• trigger infighting among the groups/people who are actively working on the true problem,
• reframe the argument to try and take power away from an actual, effective movement,
• and to flood the public discussion with noise and distraction, often with tremendous success.

This is a particularly fruitful tactic when the seeds of fear are already present, as it’s extremely easy to take an already fearful (sometimes, justifiably so) group and point them toward an imagined boogeyman, causing them to attack and fixate on a completely extraneous, possibly even non-existent, problem instead.
