Oh, I'm not really young, and I do like long form stuff, but less in the form of video content. Either reading, audio books, or podcasts are generally my longform type entertainment. I so occasionally watch 10-30 minute videos, but again most of my intake like that, especially informational instead of just comedy, is in the form of either podcast or straight text.
I work IT and I don't like video demonstrations, but instead prefer web pages that explain and give either images or text examples.
You do realize the tone of your question comes off as intentionally aggressive and inflammatory, right? It's akin to saying "so why do you beat your wife/children/significant other?" to people you don't know.
I'm black (well, a mutt) and I hate the systematic abuses done to any minority or anyone at all really, but I don't have any black lives matter flags, decals, etc despite my agreement with the movement. It's kinda disingenuous to ascribe something you've seen a few do to a whole group or movement.
