MBFC itself is biased and unreliable. On purpose or not it’s system has the effect of pushing the GOP narrative that mainstream news is all leftist propaganda while right wing propaganda is normal. It does this by not having a center category and by misusing the center lean categories it does have.
So for example national papers with recognized excellence in objective reporting are all center left. And then on center right, you have stuff like the Ayn Rand Institute. Which is literally a lobbying organization.
Not having an alternative isn’t an excuse to keep using something that provides bad information.
So you missed this comment then? And the ones where they point out any pro Palestinian source is rated badly?
