This is such a well known phenomenon I feel it falls under the "sky is blue" exception. However, here's a good example: a specific group of contributors active on pages about composers really don't like infoboxes. Despite being clear (to me) across most topics and languages that there's strong consensus on the use of infoboxes, they will not allow them on any composer's biography. Seriously pick out some random composers [1] and there's a conspicuous lack of them. If you are an unlucky editor, who stumbles upon one of these pages and think an infobox would be an easy, helpful contribution, well prepare to be bitten by a highly active, coordinated group and have your changes reverted. This has been going on for over a decade and blow up to the top levels of dispute resolution several times. [2]
Just kidding. But I do wonder - what parts are you talking about? Like some specific languages? Or topics?
