These talentless hacks always just ape whatever is popular at the time. "Angry gamer" was the "Drama youtuber" of it's day, so clearly he jumped on that bandwagon when it was relevant, and he will move on to the next thing once the "Drama" side of youtube dies down...if he has a career by then, that is.
Yup, just like I said above Charlie is a skinwalker that is following the herd. He is not alone mind you, he just happened to be one of the lucky ones with the most success, fuck knows why since he has zero charisma. Half the game is acting like you know what you're talking about as you check social media, read a few wikipedia articles and browse reddit. The real work comes with marketing and algorithm optimization, not the same dumbass video everybody else made with the same exact talking points, but worse.
