Independent fact checkers say this is false
Food hot take 5: Spice isn’t that great. It doesn’t have a flavour and it just overpowers the actual flavour of other stuff.
This is why buffalo sauce sucks.

I’ve seen many instances where the type of context can be biased, such as when unnecessary context is added. For example, when Joe Biden tweeted that he wouldn’t apologize for being the most pro-union president, context was added saying that he blocked a railroad union from striking.
Adding a true statement that is irrelevant to the point of the tweet serves no purpose except as an unneeded retort. I disagree with Joe Biden on a lot of things, but this type of context unfairly targets sources on the left. If community notes focus on retorts/spite, they are nitpicking opinions and ignoring actual lies/untrue statements within tweets. Maybe you can prove me wrong, but this kind of useless note seems to target the left more often.
Look at the helpful community notes Twitter account. I think they target both sides about evenly. I think there might be a slight bias against left-wing stuff, but even if that's true, it still is a lot more fair than anything else I've seen for combating misinformation
I agree that some type of community notes is necessary. I’m just saying that it should just focus on falsehoods, not on minor opinions. 
Unless there’s something actually false, having some kind of commenter who posts counter-opinions on every post shouldn’t be the purpose of community notes, whether its against right-wing or left-wing voices.
