I can do it too. MBFC is a hack website that equivocates between centrism and lack of bias. See this arbitrarily picked page for an example. See that graphic, the very first thing beneath the title? It’s giving the game away right there, with a left-right spectrum where the center is “least biased”. What about a centrist bias? Doesn’t exist, and the closer you get to centrist, the less “biased” you are.
