I flag all articles on politics, but not because of the rules... It's because they consistently turn into flame wars. Every single article on US politics, without fail, will have people flagrantly violating the site rules by just being hateful to whichever party they dislike. I used to get in there and flag comments to try to help combat the problem, but it got to be too much. Now I just flag the entire article because the discussions are always such low quality.
