Larry Sanger, one of Wikipedia’s cofounders, was banned from editing the site indefinitely after other editors determined he was canvassing, or in other words, calling on his followers off platform in order to influence Wikipedia’s content.
Sanger has spent more than a decade criticizing Wikipedia for what he claims is an ideological, left-wing bias on a variety of topics, and on X has framed this recent ban as further proof of everything that’s wrong with Wikipedia. The New York Post took that bait and last night published an article with the headline “Left-leaning Wikipedia blocked founder from editing site—after he campaigned to make it more balanced.”
Wikipedia editors obviously reject that framing and say that Sanger was banned for wielding his followers to sway discussion and decision making on Wikipedia. The discussion that led to the decision to ban Sanger concluded with what an editor called a “clear consensus” to ban Sanger.
reality has a well known left-wing bias
No, it's just that the right-wing has become accustomed to lying it's ass off to get what it wants.
If you base something on facts, it will be left leaning. Right leaning has a higher value in loyalty, authority, respect, and spirituality. They will deny facts if they have to in order to prioritize their other values. Right leaning people tend to be more likely to be on time, have cleaner desks, and speak more formally to someone they deem a "superior". Left leaning often could give a rats ass about authority, and respect is only given once it's earned.
All that to say, facts and reality are more left leaning by nature. Given many religious folks will deny nature's history for their spiritual beliefs.
