If a person has a shit take are they stating it as general opinion/fact or as something they themselves think? Doing accidental wrecker shit from the perspective of "I think this..." or "What about that...?" does give them an out to be criticized and corrected.

Does the person want to bring up their shit takes in the middle of other projects or discussions where it isn't relevant, demand attention, and derail the group? Do they persist in doing this after being told their shit takes can be an issue for a later time/project? Probably leaning towards wrecker.

If attempts at honestly addressing the shit take at an appropriate time/place result in the person getting angry, offended, or acting personally hurt every time, they might be a wrecker.
