Yes, exactly. I think it should be obvious [1] to anyone that Wikipedia is unreliable for extremely contentious subjects or modern politics. But if you point to those as examples of editorial bias, you get mired in of-the-moment political bickering. The reason I raise this example is to show that even in a boring area that should be unrelated to modern politics, you still see the rot.

[1] "should be" is doing a lot of heavy lifting in this sentence. Unfortunately, too many people have had their higher reasoning centers liquified by partisanship, and cannot acknowledge inconvenient facts even when they're blatant.
