Having as a prerequisite that every member of a committee have the same views, defeats the purpose of the committee to hear and debate different points of view. As radical as it seems, in many cases in the past, on a variety of subjects, after hearing the debates, people have changed their view on a subject.
To further malign this individual to say that they can't impartially chair a committee, is to also say that it is only those hand-picked by the Junior Prime Minister with the impartiality imbued in him (not - we haven't seen that yet) are worthy of consideration is a gross insult.
If recent events (small business tax, Boeing, committee chair) were a ball game Junior would have struck out at his turn at bat and be back on the bench until his next turn in rotation. 
Oh wait, he has struck out, and one of the other teams has just recruited a home-run slugger! Let the games begin!
