I was going to say that I hope this makes him reflect on his behavior but then I caught up with the rest of the thread and realized that he's actually done this way more times than I ever even knew of. That's....unfortunate as well as deeply concerning. I can't imagine ever having to know someone like that irl. One wrong move and he goes nuclear. That sort of pressure to always have to agree with someone lest you "make them" angry and lash out is really a serious situation.
As others have pointed out, it actually truly is abusive behavior. I hope he realizes that and seeks help for it. and to the ones trying to defend and excuse it even saying things like "he was provoked" ...wow. You think that kind of behavior is excusable-you really think 'provoked' is a thing? I think you've never seen domestic violence in your life. You're extremely lucky to have never seen that. Those of us who have can immediately recognize the horror in unhinged people like him, but those blessed with protected eyes and ears just think its no big deal. On one hand I'm jealous of the blissful ignorance, but on the other..its a bit embarrassing to be as old as you likely are and still thinking temper tantrums/outbursts are completely fine. That's not well adjusted adult behavior. Not even in the least.
One last thing.
To any potential XIV streamers lurking here, XIV is boring to watch. It's already a chore watching you to begin with. Dont be a jerk on top of streaming something uninteresting outside of ultimates or pvp. You're lucky you get fans in the first place that choose to hang out with you and love to see you every day. Don't snap at them and tell them off. You turned on that stream because you wanted an audience. I would understand if that audience was being cruel, but it shouldnt only take some disagreeing with you for you to fly off the handle like that. Get help and pursue a job away from people if you're that unable to control your own emotions.
