Well. Since you asked. I was on tumblr as this post was being built in 2013. The height of superwholock. Which has, since then, been declared peak cringe. So people picked new fandoms to openly love in earnest. Which were also eventually declared cringe. Eventually the youth decided to cut out the middleman, and declared loving anything in earnest to be fully cringe. So it has been a really long time since the day to day users of tumblr have let any fandom create anything nearing the cultural phenomenon that was superwholock. And it is exactly those cultural phenomena that are needed to create posts like this.
So. What happened? Cringe culture happened.
Try and imagine what would happen if this post wasn’t the “sacred texts” only ever seen in screen shots and in pinterest. Try and imagine any current pop culture detective media fandom creating this post today. They’d be slaughtered for being cringe by the time (in this case) Sherlock was mentined.
But because this post is 10 years old and completely broke containment, it’s celebrated when it graces our dashes.
