Here’s how I see it. Given how divisive modern Star Wars is, YouTubers who base their channels around Star Wars or nerd culture are left with two options to retain views. Either they “stand by the brand,” so that their channel’s success becomes bound up with the success of the franchise (Star Wars Explained, AT-AT Chat). Or they go the opposite way and embrace the vitriol, and never stop being vitriolic for fear of losing their subscriber base (Star Wars Girl, Geeks&Gamers).
But then you also have the silent third group who have done the reasonable thing and just moved on. I’ve known Prequel/George stans to fall into all 3 groups, not just the 2nd, vitriolic group.
Edit: I almost forgot about StarWarsTheory. He’s an interesting case. He seems like a decent guy. I think he just wants really badly to keep on being a Star Wars fan and keep getting excited for new Star Wars. But the sequel trilogy kind of broke him, which is why he seems so conflicted a lot of the time. (He even gave TRoS a positive review at first.)
