Notice how this works?
When a news source that is aligned with your political party gets it wrong "its ok" but when its a new source that is not aligned with your party its "spreading misinformation".
There is no objective standard for misinformation so trying to say disagreement and misinformation are not the same depends entirely on what is the issue being discussed. Any issue with ambiguity can be dismissed far too easily by just claiming it "misinformation".
