Does anyone notice Piers rarely answers a question he is asked. He always replies with another question. Someone needs to tell him that they will not answer a question unless he answers a question, and stick to it. Then, answer according to the sincerity and depth that Piers uses, letting everyone know that is how they will answer. Many of his guests have been forthright and truthful, but he has not. He is holding back to give the best propaganda.
This is what all liberals do. They dance around instead of answering a question, or change the subject.
