Is This How Democratic Compromise Is Supposed to Work?

Put aside the contentious context of the debate in question. Doesn't something just seem wrong about this?

Because a compromise must receive unanimous support to survive, Roberge was then removed from the committee and replaced with Sen. Matthew Houde, D-Plainfield, who voted with the majority. Roberge said she was disappointed she was removed.

What's the point of having a rule requiring unanimity if it means merely that a legislative body must be able to put the right number of agreeable people in a room?
