Having flaws means she's not a Mary Sue.
By definition.
You don't get to redefine concepts like that willy-nilly. Nor is Burnham's mutiny her only character flaw. She was sleeping with a Klingon agent and didn't see it. She's often arrogant or stubborn. Etc.
Yeah, no. This is flat-out wrong. Plenty of plotlines don't center around Burnham.Even if you want to say she isn't a Mary Sue....everyone always turns to her....she is always right....the whole universe basically revolves around her, without her the universe would have ended numerous times. It's written like fan fiction...
Worse, your argument applies to nearly every character in Star Trek, at some point or another. So it really seems like you just don't like Star Trek. Either that, or you're applying a double standard to Discovery.
