People who are afraid that they will get attacked if their views do not conform to the majority are more likely to flag an article and move on rather than engage with the discussion. Articles do not require 50% of the participants to flag it in order for it to get flagged, thus this minority will cause articles to get flagged. The more hostile the community get to dissenting opinions, the more articles get flagged, with the most heated topics getting the majority of flagging.
