You seem to believe that Trump saying “fake news!” is enough to consider that something is actually fake news.

If a judge in Brazil says an account should be banned because it spreads disinformation, I can go and check what was posted and decide if it’s indeed disinformation. Now I might not have time to verify every affirmation like this so I tend to trust the judicial system of any country by default, unless I have reason to believe they can’t be trusted.
