Opinion Central

Is it neccassary to have an opinion on everything? Reading the Sunday paper today, Rod Liddle appears in virtually every section pontificating zestfully on a myriad of issues, a right know-it-all. I haven't the energy to hold an opinion on so many subjects, nor the brass neck to assume I'm right on so many fronts. Is it not acceptable to abstain, surrender or concede ignorance on certain issues? Must we hold an opinion on all things great and small? If I'm to have a New Year's resolution it's to pick and choose subjects I want to hold an opinion on and be able to count them on the fingers of one hand.
