The "Angry RV Man" went viral on VHS in the 80s, and even though Google didn't exist it effectively ruined his life. There is a very sad documentary called "Winnebago Man" about his current life secluded in the mountains just to escape it.
Think of it, the last 30 years of this man's life made a living hell all so people can laugh at his angry outburst. In no way was this good for him.
"Star Wars Kid" lived through hell in high school, it certainly didn't help him either.
Its fine for you who doesn't have to live through it to just laugh it off. But these viral videos cause real harm to real people.
