Yeah, I do see where you're coming from. But just like with traditional media, Wikipedia as a "knowledge commons" maybe requires a slight left bias to guard against entrenched power and to raise awareness of marginalized perspectives.

As long as that's done in a way that protects knowledge integrity and relies on reliable sources and ethical review, I think I'm okay with that.

Also keep in mind that the age range of Wikipedia contributors skews much younger than the US population so yeah for boomers and the boomer-minded it's often gonna seem too progressive.
