He’s Not a Fighter
Sometimes people write things just to literally state the obvious, even if it has nothing to do with anything. But that’s the internet, sometimes that’s what happens. There are ways of phrasing things that can lead someone to think in a certain way or to influence what they are actually thinking. And people on the internet love to troll other people.

This person made a post about his grandfather when no one asked for it. Then somebody comes along responding to the thread that what he wrote about his grandfather couldn’t possibly be true as it doesn’t make any sense. At the end of the day, this guy just wanted to post something for the sake of posting, because he literally only pointed out random facts.
