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.
I was going to say that computing and computer science topics are free of such silliness, and that clearly you were editing a far more fraught subject area such as American current affairs; but:
hehe yeah I've noticed that. They are the most boring arguments in the world, with those people, who with a life has time for that. Well, most pages aren't like that I think.
