Felix is a bad person. He has a good sense of humor, and is generally very good at videogames, but his personality is at a 0/10. Even years ago, before he was banned from Overwatch League for a homophobic comment, it was already bad, but it has only gotten worse. He is an extremely poor sport, he has likely one of the most toxic fanbase's on Twitch, he starts unnecessary arguments constantly, he almost always shifts blame to someone else, and in general can just be extremely rude. There are many people saying "this is just what he does", but from an outside perspective, it's not funny or playful, it's just hurtful. Here's another point, Xqc would never bully Pewdiepie because he knows he would instantly get canceled on all platforms, so he refrains from ever making fun of him, but will absolutely not hold back when it comes to smaller creators like 5up, 4Conner, Adeptthebest, Trainwreck, etc. He is a bullying man child of a human being.
