Yeah, I can more or less agree with that. I didn't say Al Jazeera needed to be highly credible. I said they are factual with a certain clear bias involved. But they're doing serious journalism and the conflation of "is anti Israel" with "is lying" is a pretty common thread in MBFC, so much so that they don't even bother to hide it or pretend that anything other than them being anti-Israel is the issue that keeps them down in the not really factual category.
The reality is, they're not "mixed." They are mostly or almost entirely factual. And then, also, they have a significant notable bias. Trying to pretend that they're "mixed" factually is dishonest.
