I haven't touched these topics. But in my experience, nearly none of my edits remained, despite providing credible and neutral sources for whatever I added. Usually, there are long-term Wikipedia editors who have put plenty of pages on their watchlist, and treat the pages as their own personal property. Every tiny change is treated as if it were controversial, and must be fought over in the talk pages. Beginners to Wikilawyering and WikiBullying lose these fights. "Anyone can edit" has become a joke.
