Earlier quoted context omitted.
Wikipedia is useful for looking up technical info that there is no conflict over. It is not a good source for diving into a top-level controversial topic as those articles are long and have many places for people to stump and push for their ideas. The more specific a topic (think, a specific author associated with an ideology vs. the page for the ideology) the better. I think I've just adopted these mental heuristics…
Where would one go to dive into a top-level controversial topic? Outside of doing the research oneself or having a organization which is explicit nonpartisan with the goal of unbiased reporting (ie fact checking sites), what options are left beside Wikipedia?
If it's a scholarly topic that lends itself to testable predictions, use Google Scholar to search for highly cited and/or recent review articles, and read on sci-hub if the article isn't already open access.
If it's highly controversial and not particularly testable, then I recommend A) prepare yourself to consume a lot of primary sources and make difficult judgments on your own and B) prepare yourself to live with the problem not feeling satisfactorily resolved even if you do A for a long time.
