i think a portion of it is people who have a weird parasocial relationship with him who get weirdly confrontational and combative if they perceive someone disparaging him even slightly. i also feel like these same people probably emphasize and get invested in the streamer/twitch drama aspect of what he does that i think generally is off putting to probably most people.
i know in the past he has directly commented on stream about these people and i for some reason have a memory of him calling them "little gremlins."
