Many years ago a man wrote a funny reply to a a Twitter thread pretending not to understand the whole Vietnam-analogy of Star Wars. You could tell he was joking just by opening his Twitter page and scrolling through his older tweets.
Since then I've seen countless people sharing screenshots of that thread making it seem that this joker was being completely serious and clueless.
This bugs me every single time I see it. It is a lesson in not believing every screenshot you see posted on social media but more importantly it shows how de-emphasizing links has corrupted information sharing on the web.
