I'm sorry I think the truth is he is the complete opposite of 'the only opinion that matter is his own". I honestly can not tell if it was sarcasm becuase its such a crazy thing to say.
Nearly everything he does is to cultivate what he thinks is a cool guy image. He drinks alcohol and clearly doesn't like the taste. Eats spicy foods to prove how tough he is. Makes up stories about smelling good, fan girls wanting him, and his magic working to get revenge on trolls. Brags about a 'alcohol and drug tolerance' . He gets angry when people say dumb shit like he needs permission to go live because he doesn't want to look like depends on clint. Same reason toddler pisses him off, or he hid the camera in the corner when got evicted to hide he was in clints basement. Hell, when he gets some money he likes to buy all his straphangers free pizza or KFC to make himself look like a 'big man'.
He's actually retarded so the whole 'he doesn't care' is really he isn't picking up on shit. Whenever someone directly says something negative he shuts off. Like when Homefelon Ian asked why the fuck he was talking about kids and sickos. He can't pick up cues that it's fucked up but when someone tells him direct he gets its not a good subject. He literally split that hair dye all over himself and went into work thinking they would be fine with it -- not that he said fuck it, I recongize this isn't acceptable and i'm going anyway. Him advertising his porn habit and jerking it on discord are about only maybe not give a fuck -- but I think that is more weird fucking fetish terrority.
I love cobes but he is literally ruled by people's opinion of him. I think he has different ideas of what is important but what he does has led him to this weird goth bad boy lifestyle.
