Barack Obama Says 'Good-bye' To Long-Time Trinity Church Membership

My question is: Didn't Mr. Obama hear any of this abhorrent rhetoric from the pulpit in the 20 years he and Mrs. Obama attended Trinity? Surely, he was aware of the views of his pastor prior to this election year? Why did he tolerate it then? Or did he? I think this is the more important question - are we, as members of a church, accountable for the beliefs of our pastors?
