For anything even remotely controversial, I stick exclusively with primary sources and ignore Wikipedia. The site is clearly compromised by admins who only want left-leaning secondary sources summarized. If you come across a controversial topic with biased, or even faulty information, the admins will remove edits which don’t comply with their bias, ban persistent users, and eventually “protect” the article. Even one of the co-founders has railed against the current state of the site.
