Are you trying to say that stars get treated differently than marginal players? Of course they do.
There's not a way around that really. Turner got benched for somewhat similar behaviour, but maybe not quite the showing up the team or manager element. It's not like they are going to release Turner for that.
We don't everything going on either. After the Turner thing, maybe a warning was sent that the team wasn't going to tolerate anything like that. Maybe the bullpen has been a catty mess all season and when they jettisoned Kintzler, they had a talk with the rest of the bullpen saying we need the rest of you guys to buy in and start acting like a team, and Kelley's tantrum would look pretty bad in that context.
