Screenshotting and posting tweets that provoke emotional outrage has become the norm. All parts of the political spectrum use it. 90% of the time, the claim in the tweet has zero source to back it up. The information is accepted without question because it is propagated on forums where the audience leans towards the message being sent.
A screenshot of a tweet saying "everyday in america, 250 black men are hunted down and killed by police", it will make it to the front page on reddit (esp in 2020).
Likewise, a screenshot of a gab or parler or tweet saying "trudeau is literally worse than stalin because he had the police evict the convoy protesters", it will make it to the front page here because the people will eat it up.
None of those messages are true, but they're short texts that can be quickly read by their target audience and provoke an emotional response the further push the person into their hole of an echochamber.
Be careful of what you upvote. Use critical thinking. Have emotional control.
