Someone who derails a discussion or functioning of a group, whether
intentionally or unintentionally. Frequently used in leftist (socialist/communist) circles, often with aspersions of being a spook, cop, or COINTELPRO infiltrator.
Examples of wrecker behavior include:
* exclusively focused on condemning shortfalls while exhibiting zero interest in discussing or acknowledging any solutions that are suggested
* endless
questioning of the proper forum for the topic at hand
* being excessively pedantic when it benefits them, yet quick to misrepresent others' views/statements
* long tangents, or just taking up an outsize percentage of airtime about themselves and their
individual concerns
* revisiting topics that have already been settled, or just repeating themselves in general at great length
* attempting to exert their own
individual influence and control over a democratic/consensus decision, and becoming very agitated/verbose if they do not succeed in swaying
others
* incendiary comments intended to (or effectively serve to) distract and stir up drama, especially in a public forum. This often includes targeting those they expect adversarial responses from. Closely resembles trolling.
