As it turns out, the "Neutral Point of View" rule that Wikipedians so proudly tout is quite strongly biased toward a specific world-view: that of the so-called "progressive" mindset.
It doesn't matter how much value a system of ideals has; if it transforms a purportedly neutral source of information into a dogmatic one, then the source loses all credibility and usefulness.
This seems to be happening on Wikipedia at an alarming rate, which is a real bummer. It's not as ridiculous and blatant as (e.g.) Conservapedia, but... well, frankly, that makes it all the more concerning. Zealotry is way harder to call out when it's cloaked, as Wikipedia tends increasingly to be, in the sly guise of unassailable moral high ground.
