Life is a meaningless crawl towards the heat death of the universe. Childish behavior is the most appropriate attitude one can have towards most things.
I totally agree with you, and there are definitely more whimsical ways to go about it than goatse. Even if I personally can find whimsy in getting randomly goatse'd I'm not gonna say that someone who finds it really disturbing deserves what's coming to them just because they are insufficiently chill.
I found a link on HN a while ago that shows you just that, it's a randomizer (like the old StumbleUpon) that sends you to random "old internet" webpages: https://wiby.me/surprise/
It sent me to a 1998 page about phrenology, the 'science' of determining someone's mental traits based on indentations in their skull: https://www.phrenology.org/index.html
If you were on forums in the aughts, it was unavoidable. I think every very online millennial knows what Goatse is. The youngest millennial is 27. Which begs the question: is Goatse what spreads Zoomers and millennials apart?
