:::Controversial material should be posted to a BLP's talk page first, but mundane biographical details should be integrated directly.  Claims like "His election is obviously a disaster for all gays, women and atheists worldwide" would fall in the former category.  A less polite way of saying it would have been, "Please don't try to post that in the article because undoing and rollbacking is hard when there are edit conflicts."  To be fair, I have been in discussions where one editor has tried to take ownership by demanding that all posts and sources be discussed and given approval before adding, and it can be infuriating, so I'm no absolutist.
