Dude may be an introvert, they tend to dislike engaging in arbitrary norms unless they understand and agree with the purpose. Being a Black Male introvert is difficult because you often have the expectation that you be "on". Whereas white dudes have greater license to introverted, especially if they are highly talented or skilled.
Since when did being an introvert equate to being moody?
It has nothing to do with being an introvert. Kawhi Leonard is a TRUE introvert and it's not a problem. He comes in with a quiet demeanor and people accept it. We aren't going to say Leonard is moody right? Does he cause drama? No, because his behavior is very consistent.
Joe Johnson is an introvert. Was it really a problem?
People like consistency. Moody is inconsistent behavior, which are the traits Irving exhibits. No one likes trying to figure out if this mufukka is cool today or if he's going to be a bitter bytch ass nygga.
Yall really gotta stop making excuses for bytch ass nyggas, because you like the way they bounce the ball. How do yall not know the difference between an introvert and a person that displays mixed signals and is acting like a weirdo?
