What does Holden dislike about Carl?

From the text:

But that was one of the annoying things about Luce. When we were at Whooton, he'd make you describe the most personal stuff that happened to you, but if you started asking him questions about himself, he got sore. These intellectual guys don't like to have an intellectual conversation with you unless they're running the whole thing. They always want you to shut up when they shut up, and go back to your room when they go back to their room. When I was at Whooton old Luce used to hate it--you really could tell he did--when after he was finished giving his sex talk to a bunch of us in his room we stuck around and chewed the fat by ourselves for a while. I mean the other guys and myself. In somebody else's room. Old Luce hated that. He always wanted everybody to go back to their own room and shut up when he was finished being the big shot. The thing he was afraid of, he was afraid somebody'd say something smarter than he had. He really amused me.
